Haswell specific linux-ck doesn't work with Haswell CPU - Intel G3258?

I tried to install Haswell optimized linux-ck. Systems always freezes at boot, after kernel and init ram disk are loaded. After some time of troubleshooting I've tried generic linux-ck kernel and it works.
My question is, why Haswell optimized linux-ck doesn't work on Haswell CPU - Intel G3258?

Despite being labeled as such, it doesn't have the full Haswell feature set. Among other things, AVX and AVX2 are missing. If the compiler generated code which uses AVX/AVX2 instructions, their lack can definitely cause the kernel not to boot.

  • My MSI KT3-ULTRA2 doesn't work with my CPU cooler!!

    My MSI KT3-ULTRA2 doesn't work with my CPU cooler!!              
    I've got an MSI KT3-ULTRA2 mainbord, and I have a NEOLEC VENEZIA TB Cooler. But when I attach my NEOLEC cooler and I start the machine, the machine shuts down within a couple of seconds, and I get nothing to see on my screen. The weird thing is when I turn the PC on, the cooler starts rotating so it can't be broke, but then the pc shuts down i a couple of secs. So pleezze anybody help me!!
    The weird thing is that I also have a coolermaster cooler, and that one works fine. But the problem is that this coolermaster is designed for AMD XP 1900+, and I ahve an AMD XP 2200+ that's why I bought the Neolec Venezia TB cooler.

    one easy thing to watch for... see if the heatsink or fan is in contact with any part of the motherboard, like... if it is too big and touches something that normally wouldn't be in contact with a fan or heatsink.  If so, it could be shorting it.

  • Satellite M40-129: PCMCIA Card doesn't work with Linux

    I have D-Link DWL-G650 with Atheros Chipset which is good supported under linux (madwifi). But if I boot Linux the card is not found. I tested the card with an Fujitsu Siemens Notebook and it worked out of the box!
    Any idea why it doesn't work with my M40-129 ?

    Hi
    Like you know Toshiba doesnt support the Linux and there are no Toshiba drivers for the Linux OS but I was able to find this useful Toshiba page about the notebook configuration with Linux:

    You should check the OS machine compatibility and the other areas.
    Im sure you will find many useful tips.
    Good luck

  • Numbers 3.2 has changed too much, it doesn't work with my project anymore. How do I revert back to the previous version I was using?

    Numbers 3.2 has changed too much, it doesn't work with my project anymore. 1) The sheet panels used to be on the left hand side and easily reviewable and searchable, but now they are on the top and it's harder to find a specific folder without scrolling (too time consuming), 2) I used to be able to duplicate a folder within my sheet panel window by simply clicking on a folder and hitting Command D, but that doesn't work now so it looks like I'll have to spend even more time to recreate the same tables that used to be easily duplicated, and 3) I can't choose fill colors that matched my project anymore because there are only limited choices available now. And these are only the changes that I'm aware of. I am very disappointed and frustrated. Whatever the motivation was to limit Numbers 3.2, I want the previous version back. How do I revert back to the previous version I was using?

    The sheet panels used to be on the left hand side and easily reviewable and searchable, but now they are on the top and it's harder to find a specific folder without scrolling (too time consuming),
    You can scroll more quickly between sheets if you don't use the left-right triangles, but instead move the cursor up into the bands with the "tabs" and drag right or left.
    Also, if you have a lot if sheets for which you want a quick vertical list, then you can try the following have something like this pop up (showing your sheet names automatically) whenever you hit a keyboard shortcut (in my case shift-command-j):
    This is done via a Jump to Sheet Automator Service (Dropbox download).  To install just doubleclick the .workflow package and (if needed) click 'Download Anyway' in System Preferences > Privacy & Security.
    This will cause a new item to appear in your Numbers > Services menu.  Then, if you want a keyboard shortcut, go here in System Preferences and add one:
    You can rename or remove the service by holding down the option key in Finder and choosing Go > Library > Services. You can also view the AppleScript contaned within the service by opening the .workflow package in Automator.
    This particular service jumps to the first cell of the first table of the sheet you choose from an automatically generated list of all sheets in the current document.

  • The mouse scroll wheel doesn't work with Xorg

    I recently installed Solaris 10 on my x86 box. One issue is that the mouse scroll wheel doesn't work with Xorg. Hmmm... Okay, it sometimes did work, and most of the time went on strike, and recovered at random. This pattern continued.
    My mouse is an ordinary PS/2 one with two buttons and a scroll wheel. I want to promise that there's absolutely nothing wrong with it per se. Here is some info:
    $ uname -a
    SunOS arbiter 5.10 Generic_127112-07 i86pc i386 i86pc
    $ grep -i mouse /var/log/Xorg.0.log

    (II) XINPUT: Adding extended input device "Mouse0" (type: MOUSE)
    # The section about mouse in /etc/X11/xorg.conf follows:

            Option      "ZAxisMapping" "4 5"
            Option      "Emulate3Buttons" "false"
    EndSection
    # Note that the only result of explicitly changing protocol to ExplorerPS/2, PS/2, IMPS/2 or whatever else is that the cursor jumped here and there and everywhere when I moved the mouse.I ever post one in comp.unix.solaris to ask for help but got no effective solution. Thank you all.

    You remember correctly, Yvan.

  • HttpServletRequest.isRequestedSessionIdValid() doesn't work with SSL

    In OC4J 9.0.3, when SSL is enabled, the call to
    HttpServletRequest.isRequestedSessionIdValid() method doesn't seem to work. It always returns false when it is called even though the session has not yet expired.
    On the contrary, when SSL is disabled, the HttpServletRequest.isRequestedSessionIdValid() works correctly as specified in the servlet specification.
    Can anyone in this forum explain to me why HttpServletRequest.isRequestedSessionIdValid() doesn't work with SSL? Any solution for that problem?
    Thanks in advance.

    I might be wrong, and if I am wrong then could someone correct me, but as far as I knew, Creative Cards do not support Windows Server 2003. I maybe wrong, have you tried the latest BETA driver (see exciting news thread)John
    In windows 2003, the driver works if I limit the total ram to 4096MB by adding /Maxmem=4096 in boot.ini file.
    FYI
    /maxmem
    The /maxmem parameter limits the physical memory available to Windows.
    /maxmem=SizeInMB
    Subparameter
    SizeInMB
    Specifies the maximum amount of physical memory available to Windows. Enter a decimal number that represents the amount of memory in megabytes.
    Comments
    This parameter actually limits Windows to memory addresses less than or equal to the specified value. Because some memory within the remaining address space might be reserved for nonsystem use, the actual memory available to Windows might be less than the amount that you specify.
    The /maxmem parameter is supported only on Windows Server 2003, Windows XP, and Windows 2000. On Windows Server 2003 and Windows XP, use /burnmemory to limit system memory more precisely. On Windows Vista and later versions of Windows, use the removememory or truncatememory parameters with the BCDEdit /set command
    You can use this parameter to test a driver in low memory conditions. For example, you can use this parameter to limit a computer with GB of memory to 256 MB of memory.

    DON'T BUY ANYTHING FROM FORMAC! They make quality products, but their customer service is a big time joke! They won't take care of you.

    What have you tried?
    You are going to get nowhere quick with the 6.1 utility in Mountain Lion if this is the only OS you have available.
    Look up how to install 5.6 utility under ML. At least then you can see printers. That is assuming you are trying to use USB.
    Has this worked ever on Mountain Lion? Did you download the drivers for that printer for ML?
    Plug it into a computer directly.. does it work? If it doesn't work locally it sure will not work via the network.

  • Quicklook doesn't work with .avi files

    Hello, i've got a little problem right here on my mac. The thing is that I used to have Snow Leopard as a OS and quicklook used to work great, it opened all the extensions I used to work with. The thing change when I format my HDD and installed a clean copy of Lion OS. Now quicklook works fine as it used to but not any more with .avi files. I remember that this feature was working great on my previous OS, and it's really important for me to find a solution because quicklook is an absolutely amazing feature of our Macs.
    I've tryed to download plugins, restoring permissions or even trying it with a guest user, but no success.
    Please help me. If you need more info about specs or something i'll be glad to give them to you.
    Thank you!!!

    Going to the local Apple store this morning...
    My problem is not uncommon as the board is showing signs of this happening to many others as well. That is where I found the restore and reboot information to try to solve the issue of crashing apps.
    I understand that Apple will not "give away the cow", but letting iPhone users know that the problems they are having are being addressed by Apple is a little more comforting than nothing at all. Other wise, all the apps in world are useless and even more importantly worthless, if a person has to reset/reboot/reload just to get them to work.
    IF Apple can not address the basic problems with todays iPhone apps, why should one believe that the iPhone 3.0 OS is any better? Using a PC comparison, which is better, XP or Vista. If the current iPhone OS of 2.2. what ever is not working that well (as related to down loaded apps and iTunes), will OS 3.0 be any better?
    The waste of time I refer to is in going to the apps store and downloading the apps... Again why by apps if the free version does not work?

    No, that's a rather silly conclusion.
    There are two options:
    stop using the crappy router provided by the ISP.
    Physically connect the ATV to the router via Ethernet.
