T5120 with a linux Kernel embedded in firmware

I need to re-purpose a T5120 (i.e., reinstall Solaris 10 & selected apps),  but in a previous life this box was apparently used as a SPARC based VM Manager; there is a small linux kernel which boots immediately upon connection to power (power button not pressed). I've found no way to interrupt or disable this process. Furthermore, after this firmware startup is complete, you're prompted for login credentials, which, of course,  no one can remember. 
Using a laptop with CentOS 6.3 and minicom to "tip" in.
I need to know what must be done to make this a "normal" T5120 one again.
TIA

Hello
What login credential are you requested for solaris OS or for ILOM?
If it is OS, then you can put the auto-boot to false using the ILOM
Avoid Booting the Solaris Operating System at Startup - SPARC Enterprise T5120 and T5220 Servers Topic Set
If they are ILOM password and you don't remember it, this docs could help

  • Upgrading Oracle Linux with Oracle Unbreakable Linux Kernel

    Hi all.
    I'd like to upgrade an Oracle Linux OS with unbreakable linux kernel.
    Current version is :
    [oracle@union ~]$ uname -r
    2.6.18-164.el5PAE
    Which steps needs to be performed?.
    I know i must be at 2.6.32. Also Unbreakable Enterprise Kernel is available for x86-64 servers.
    Q: How do i know if my distro is x86 or x86-64?
    Regards, Luis ...!

    Do i need to download a 64bit distro?.

  • Screen lags with catalyst and kernel linux-3.10.6-2

    so I have been using arch for about a month now and it has been working fine. But since I installed linux-3.10.7-1 my screen started lagging.
    when moving windows around the screen lags and when scrolling down in thunar it lags very much.
    And I can't configure my monitors anymore in catalyst control center. same thing with the latest kernel: linux-3.10.9-1
    so I downgraded to linux-3.10.6-2 for now and everything works fine.
    catalyst version is catalyst 13.4-15, catalyst-utils 13.4-3
    xorg version is xorg-server 1.13.4-1
    I'm using openbox btw version = openbox 3.5.2-1
    GPU = AMD Radeon HD 7850
    Any idea what might cause this ?

    Is the fglrx module loaded at all?
    And what's the output of 'fglrxinfo'?
    Most likely the fglrx module is incompatible with the recent kernel version.
    A simple solution for this problem is using catalyst-hook.
    THIS. You should do this because the kernel module in the catalyst package itself is compiled against the kernel Vi0L0 has on his/her system and there is no way to compile one for later kernels without installing the package Radioactiveman suggested.

  • [WORKED AROUND] Installing Arch Linux with 3.11 kernel on Vaio Pro 13

    Yesterday I received my Sony Vaio Pro 13.
    The WLAN card is only supported since kernel 3.11, which has been released by Linus several days ago.
    The laptop has no ethernet port, ideally I'd thus use the WLAN abilities using installation.
    Since there is no Arch ISO available with 3.11 yet, I was hoping to create my own, using the arch wiki guide on remastering the ISO: https://wiki.archlinux.org/index.php/Re … nstall_ISO
    I was wondering whether, instead of compiling my own kernel, I could just chroot into the unpacked ISO filesystem and install the 3.11 kernel from the testing repository using pacman.
    Which, as far as I could tell, was the released kernel, and not an earlier RC. Is this possible?
    One other question remains: the author of this blog mentions a diff that is needed to prevent the CPU freq to be stuck at 800Mhz (http://elouisyoung.blogspot.se/2013/07/ … -with.html).
    Does anyone know whether this made it to the mainline?
    # UPDATE
    I explored the latest kernel release and found out that the patch is not yet included in the mainline.
    So I'll have to compile my own kernel. There are however still issues with the CPU freq scaling (won't scale lower than 1.6Ghz). Nasty...
    # UPDATE 2
    Booting + installing mainline ISO, installed testing/linux for wifi, compiled own kernel + installed besides the testing/linux kernel worked fine for me.

  • [Solved]The linux kernel with build in bootloader?

    First of let me apologize if I'm making no sense at all. This isn't really my area of expertise.
    I just recently stumbled upon some rather interesting "news" about the linux kernel developers working to implement a an EFI/GTP (I think) bootloader in the kernel it self. I would very much like to know if this is actually true, I'd like to learn more and follow the development, but I haven't been able to find any relevant information, appart from the incomplete mailing list I stumbled upon.
    I suspect that I'm simply using the wrong search parameters. Again, it's not like I know too much about what I'm doing.
    In any case, if you have even the slightest idea what I'm talking about, please do guide me in the right direction.
    Best regards.

    Thanks to the info and links the.ridikulus.rat provided, I've now learned a bit more about this stuff (I'm probably still missing a lot ). Basically, rEFIt is a manager that launches bootloaders. With EFI_STUB, the kernel is it's own bootloader, so what you say is indeed possible - start linux from rEFIt without going through grub/syslinux. Well, it would be possible if there wasn't for one huge problem - rEFIt doesn't allow passing options, which is needed in this case. But that's where rEFIt's fork (rEFInd) comes into play.
    Further, there are patches on the kernel mailing list that will make it possible for an EFI_STUB kernel to read options from a file. Then not even rEFInd will be needed. Strictly speaking it isn't needed even now, but you need to type the options manually on the efi shell, which isn't very convenient. Fun stuff all this, innit? . It's a whole new crazy world.
    Cool, thanks for the pro-active research!

  • Oracle Unbreakable Enterprise Linux come with an ndiswrapper kernel module?

    Hello
    Does Oracle Unbreakable Enterprise Linux come with an ndiswrapper kernel module?
    Does Oracle Unbreakable Enterprise Linux come with a package for the ndiswrapper kernel module that matches the kernel version?
    What wireless driver is compatible with Oracle Unbreakable Enterprise Linux?

    Hi,
    Oracle Unbreakable Linux does not come with any ndiswrapper kernel module and any package for ndiswrapper module. But it includes many wireless network drivers. You can look at them from kernel package. For example
    rpm -qlp kernel-2.6.18-8.el5.i686.rpm |grep wireless
    From the output, you can find which wireless drivers are coming with Oracle Unbreakable Linux kernel.

  • HP DV6000 randomly freezing with Arch Linux

    Hello,
    Just to clarify I am working with Arch Linux as a Web Developer, therefore I do have special needs such as having 20+ tabs open with vital information in different pages.
    I can assure that after using Windows XP, Windows 7, xUbuntu, Linux Mint and Ubuntu I have never had such breaks or freezes in this machine.
    The freezes are identifiable when the mouse seems to be very slow to move, the computer very slow to respond, the cursor of the icon does not change within the context where it is, I can't even open the menu bar to access the terminal (using Terminator).
    After noticing these randomly freezes, I've started to keep the Terminator open with top command inserted. After seeing the values of percentage usage in CPU or RAM, the levels don't even go up more than 20%. However, I notice that the laptop suddenly starts heating a lot.
    The solution is just to wait with some luck about 10 minutes. If it does not go on after that, I need to turn off the computer by pressing the button or unplugging the battery (yeah, the battery is dead too).
    Some main packages I currently use are:
    - Cinnamon
    - Filezilla
    - Netbeans PHP IDE 8.0
    - Skype
    - Geany
    - 7-Zip FM
    - Adobe Flash Player
    - Chromium (my main browser)
    - Firefox
    - SSH
    - Htop
    - VLC Media Player
    - Terminator
    Any ideas of what could it be?
    Thanks!

    Yes, you are correct, I do not have any swap. Would I benefit from it? I guess I never used it.
    After the occurance you mean, after the freeze? I will try to do it, but it is rare the case when the computer is able to not freeze at all.

  • [SOLVED]problem with Bumblebee and Kernel 3.11-1-2

    Hi!
    I'm having problems with Bumblebee from Kernel 3.10 but I read that Kernel 3.11 solved the problem, I searched and tried possible solutions to my problem unsuccessfully
    The message shows me when I run "optirun":

  • Linux: Kernel Preemption, To Enable Or Not To Enable

    The default 2.6.4 Arch Linux kernel .config has 'CONFIG_PREEMPT=y'. 
    Not everyone has been happy with kernel preemption, however.  There is an interesting discussion of this under the title "Linux: Kernel Preemption, To Enable Or Not To Enable at http://kerneltrap.org/node/view/2702
    The text of the article is repeated here:
    "A recent bug report on the lkml complained of significant performance degradation from enabling CONFIG_PREEMPT, kernel preemption. 2.6 kernel maintainer Andrew Morton [interview] pointed out that such degradation from enabling kernel preemption is not normal, instead likely from it triggering a bug. However, an interesting conversation on the merits of kernel preemption followed.
    Andrea Arcangeli, author of the 2.4 virtual memory subsystem, bluntly suggested, "keep preempt turned off always, it's useless. Preempt just wastes cpu with tons of branches in fast paths that should take one cycle instead." Andrew Morton noted, "preempt is overrated." However, he went on to point out that kernel preemption has been very useful in detecting locking bugs. He added, "it has been demonstrated that preempt improves the average latency. But not worst-case, because those paths tend to be under spinlock."
    Robert Love [interview] replied directly to Andrea's comments saying, "I think you are really blowing the overhead of kernel preemption out of proportion," going on to agree with Andrew's statements. He further explained:
    "I also feel you underestimate the improvements kernel preemption gives. Yes, the absolute worst case latency probably remains because it tends to occur under lock (although, it is now easier to pinpoint that latency and work some magic on the locks). But the variance of the latency goes way down, too. We smooth out the curve. And these are differences that matter."
    There is more discussion and feedback with the article (including the original bug report).

    I like preemption. it the "democracy" heaven of processes and threads. This post was interesting, but the point is this bug..?
    if the bug is found, who can say that preemption in the kernel is not a good idea?
    thanks for posting though ;P

  • [SOLVED] Linux kernel 3.9.2-1 bug - hp_wmi dmesg errors (hp nx9420)

    My laptop is hp nx9420, the RAM and hard drive are pretty much new and are surely fine, and I'm using 64-bit Arch. The No Execute bit has always been enabled.
    Upon upgrading my system, which pulled the kernel package linux-3.9.2-1, and after a reboot, there were problems regarding the boot process and it appears it's a bug connected with hp-wmi. Also, my system can't properly unmount the root partition and reboot/shutdown.

    I removed the powerdown package thinking it was the culprit, but it isn't.
    Currently, I solved this problem by downgrading to an older kernel.
    What could possibly be the cause?

    Quite obviously, this is related to HP laptops. Perhaps blacklisting the hp_wmi module could solve it. However, that module might be related to the extra buttons and/or to reporting the state of the hardware rfkill switch...

  • Problem with ACPI on kernel 2.6.12.2-1

    I am using a HP Pavilion ZE4805US laptop and since I upgraded the kernel to 2.6.12.2-1 it will not finish the bootup unless ACPI is off. the last line it about the ide devices in the computer (didn't write it down, will post later)
    here's my /var/log/kernel.log since the last bootup, since it does not seem tolog unsuccessful ones (thebootup before was an unsuccesful try with nolapic, and yet the log shows it got to networking and to ndiswrapper, which happn after the stage in which it gets stuck)

    We had the same problem with the PL/SQL cartridge (OWS-04764 ...). We solved our problem with a new kernel. Its important that you have a kernel with symmetric multi-processing support (SMP) enabled, independent if you have a one or two processor machine.
    I hope it will help you.
    Best regards

  • How to setup grub2 with arch linux and xen, lvm on luks

    OK, so I tried downloading this package from AUR:  https://aur.archlinux.org/packages/xen-git/ , but that has patching problems as noted in the comments.  It looks like the packagebuild sets up all the xen stuff for you, but I can't seem to get the package to install because of the error's while patching.  If anyone can point me in the right direction on what all the extra files in the PKGBUILD are for or how to debug problems with PKGBUILDs not working because of patches.
    So next I just tried to compile the latest xen from git://xenbits.xen.org/xen.git (with ./configure, make, make install) and that seemed to go fine, but I'm a bit confused:
    1.  Do I have to do any additional configuration for xen when working with arch linux?  On ubuntu I could just compile the source, update grub, and make sure to start the x services at runtime.
    2.  How do I set up grub to load xen with this setup?  Right now this is my /boot/grub/grub.cfg:
    GRUB_DEFAULT=0
    GRUB_TIMEOUT=5
    GRUB_DISTRIBUTOR="Arch"
    GRUB_CMDLINE_LINUX_DEFAULT="quiet"
    GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda3:vgStorage"

    #GRUB_TERMINAL_OUTPUT=console
    # The resolution used on graphical terminal

    # Uncomment to disable generation of recovery mode menu entries
    GRUB_DISABLE_RECOVERY=true
    # Uncomment and set to the desired menu colors. Used by normal and wallpaper
    # modes only. Entries specified as foreground/background.
    #GRUB_COLOR_NORMAL="light-blue/black"

    #GRUB_SAVEDEFAULT="true"
    ~
    I've tried throwing in a line like: XEN_HYPERVISOR_CMDLINE="cryptdevice=/dev/sda3:vgStorage", but nothing new shows up on the grub boot menu.
    First time trying to set up a non-ubuntu system, please help!

    As for XEN.... well you could always try QEMU/KVM or LXC.
    As for the LVM2-on-LUKS/dm-crypt
    My /etc/mkinitcpio.conf looks like this...
    MODULES="aesni_intel ata_generic ata_piix nls_cp437 ext4 intel_agp i915 dm-snapshot"

    FILES=""
    HOOKS="base udev autodetect block keymap encrypt lvm2 filesystems keyboard fsck shutdown"
    /etc/defaults/grub
    GRUB_CMDLINE_LINUX="cryptdevice=/dev/sda2:root:allow-discards"
    GRUB_PRELOAD_MODULES="part_gpt part_msdos"
    GRUB_TERMINAL_INPUT=console
    GRUB_GFXMODE=auto
    GRUB_GFXPAYLOAD_LINUX=keep
    GRUB_DISABLE_RECOVERY=true
    The running grub config looks like this
    /boot/grub/grub.cfg

    98 echo 'Loading initial ramdisk ...'
    99 initrd /initramfs-linux-grsec.img
    100 }
    Things to note:
    Numerical UUID is the UUID of the ROOT partition.
    Alphabetical UUIS is the BOOT partition
    hd1,msdos2 AND ahci1,msdos2 are how the Grub Bootloader numbers the drives not Linux.
    I have my BOOT partition on a USB stick, and it is the Second partition.
    So, that would make it, Device 2 and Partition 2
    Device numbering starts at 0
    Partition numbering starts at 1
    Oh, and note that you don't need ":allow-discards" ... at all but certainly if you don't have an SSD. Also note that I included the line numbers so it is very clear that I didn't post the whole thing, but instead what I thought was relevant. Finally, I am loading modules that I don't even need, but what the hell... if it ain't broke, don't fix it

  • [SOLVED] Intel i7-3920XM Laptop CPU Linux Kernel Support

    Recently, I purchased a laptop with an Intel i7-3920XM CPU, with the intention of utilizing it for scientific computing (I've become strongly interested in machine learning and artificial neural networks).  Supposedly, the CPU has a variable clock speed of 2.90 -- 3.80 GHz, which would be great, but my kernel has throttled it to 1200MHz.  I've tried both the cpufreq performance and userspace kernel modules (configured for performance), but the laptop stubbornly refuses to increase the clockspeed more than 1200MHz; I gave up on cpufreq and have uninstalled it.  I've read some accounts that it is possible that the Linux kernel may not support my CPU yet --- does anybody know if that is the case?  If it is not, can anybody point me to some literature describing how to un-throttle my CPU?

    You should just leave things as they are, if you can actually feel sluggish performance ( I don't with 6 cores @ 1200MHz) you can try this:-  https://wiki.archlinux.org/index.php/Cp … erformance
    Which will liven things up a bit at the cost of more battery juice.
    EDIT/ compile something and whilst compiling
    cat /proc/cpuinfo | grep MHz
    to see what's reported at full load, but be aware it still may not report correctly due to turbo.

    I would agree with you if that was what the argument was about. I said the same thing about i7z as you just did, which is why i suggested it. as I understand it. your telling him 1.2 Ghz is an acceptable min and i would agree.How i am interperting his thread is 2.90 Ghz is his base. 3.80 Ghz is his max turbo. His CPU under 100 % load will not rise above 1.2 Ghz despite his stock clock is actually 2.90 Ghz. I can honestly say that this is the more likely story because my i7 did the same thing. on battery the max it would clock up to while runing /dev/urandom > /dev/null was 1.2 Ghz, while on Ac it would even turbo correctly. by unloading the module.  my proccessor would clock as expected 800 mhz min 3.4 max turbo. and if you look he even used the performance governor to try to increase the clock
    Ya, really the OP did not tell us 'how' he was reading his CPU speed....

    runny6play: If deltaecho is also seeing these same slow speeds in i7z then both you and he should look into your BIOS settings. For sure this would be a BIOS setting on a ThinkPad. "If on battery....slow... if on AC...fast".
    Yes, it is the Linux Kernel that is no "Reporting" the correct speed. This is a known bug. However, there is nothing wrong with your CPU. It is running at High Speed.. Like this is the read out from my Kernel at idle...
    [user@archtop:~]% sudo cat /proc/cpuinfo | grep MHz
    [sudo] password for user:
    cpu MHz : 1200.000
    cpu MHz : 1200.000
    cpu MHz : 2901.000
    cpu MHz : 1200.000
    The BEST way to test your CPU is, again i7z then compile some code... Like change the MAKEFLAGS="-j4" to -j1 for 1 thread, -j2 for 2 threads.... and so on. Compiling software will push your CPU all the way up.
    When testing like this, i7z will show on 1 thread my CPU runs at 3.6GHz, on all 4 threads it runs at 3.4GHz, as it should. However, /proc/cpuinfo will only say wacky stuff like cpu MHz: 1200.000 cpu MHz: 2901.000
