Device-mapper not working after kernel update

Hi, yesterday i've upgraded kernel to 2.6.36 and I was so happily so i rebooted immediatly, but it ended up with error. that it can't found /dev/mapper/archarray-archroot, which is, of course my root partition.
I'm using to raid1 partitions:
/dev/md0 with boot ext2 partitions (archboot partition)
/dev/md1 with LVM (volume group arrcharay, partitions archroot, archvar and archdata)
When in sandbox i've tried lsmod and i see, that i have raid1,ext2,ext4(root partition),md_mod and dm_mod loaded(and some more of course), so i think there's nothing missing to fire-up root partition.
I've tried to boot up install (from USB stick) and mount root patition with following:
modprobe dm_mod raid1
mdamdm --examine --scan >> /etc/mdam.conf
mdassemble
vgscan
vgchange -ay
And it worked, so my disk nor LVM setting is not broken.
Only thing that i think i can did wrong, is that i've commented /dev/md1 entry in /etc/mdam.conf. I was confused by "name=archiso:1" because i haven't use "archiso" anywhere when creating LVM volumes. So i thought i will try it, and if anything go bad, i will undo this. But it worked ... until kernel update.

It was problem with my badly edited /etc/mdadm.conf, so I'm sorry for this.

Mic Jack not working after Driver Update, Console unavailable, can't install

LMic Jack not working after Driver Update, Console unavailable, can't install? I've had nothing but problems after downloading the latest updates via the auto-updater.
I'm currently using the Creative SB X-Fi Pro Series card. I've had it for close to 6 months and have not had any issues until I ran the auto-updater last night, and while it downloaded over 250Mb of updates, all of them failed to install as described below.
I'm running on Windows Vista Ultimate, 64-bit
My main issue is the fact that my microphone is no longer working. I've done a lot of searching and I think the problem has to do with flexijack not being a microphone jack, but instead is an 'in-line' jack. I can no longer find my audio control console, which allows me to switch between gaming and entertainment modes, ect. The solution I found on the KB says that you can switch the blue jack on the back of the card from an in-line jack to a mic jack within the Audio console. I tried downloading it, but while going through the install, I get an error saying the files could not be found and a prompt which asks for a disk or file location. The same thing pretty much happens with all of the items I attempted to download and install.
I was able to run console fine, as well as use my mic yesterday before I attempted any updates. I attempted the updates because since I've had the card, I've had issues where after I exit a game, all my sound will become crackly and static. Before, I would simply open up the console and switch back-and-forth from gaming to entertainment, which would fix the problem most of the time. If that didn't work, a restart would fix it, but now I've opened up a whole new set of issues.
Any help would be greatly appreciated.
I also want to say that the support tickets should not require a serial number to submit a new ticket. My product is registered, so I got rid of the box which contains all that information, leaving me at the mercy of these boards...

Hello all. Fisrt of all, this are my specs: Yoga 2 pro 13". WiFi card: Intel(R)Dual Band Wireless-AC 7260. I bought it from Best Buy on November 27, 2014. If you aquired your Yoga before this date, you may have the single band WiFi card. As many of you have experienced, I also had a bunch of issues with my WiFi connectivity and this is how I was able to solve it. At least it has been a couple of days that I haven't had any issues. The first symptom was the usual connection drops every X amount of time. For me it was about every 2 hours. I first unchecked the "Allow the computer to turn off this device to save power" option in the Power Management tab of device manager and disabled U-APSD support in the Advanced tab of device manager. This action did not solve the problem. I then downloaded and updated the driver from the Intel web site (http://www.intel.com/p/en_US/support/detect) and this seemed to solve the drops; however, a new problem arised: Everytime my Yoga would wake up from sleeping mode, all my wifi networks were gone and the adapter showed as disabled in Device Manager. I would have to anable it to have my networks back. It was a solution but a pain the butt to have to do this everytime. After hours of reading post after post in several forums, I read a repy from Lenovo asking to try leaving the "Allow the computer to turn off this device to save power" CHECKED if you were using the latest version of the driver. I went back to device manager and checked it back and that seems to have solved the problem. So far I haven't had any drops and everytime my laptop comes back from sleeping mode the WFi connection is still there! Here is a recap of how everything ended up: -The driver version I installed is 17.1.0.19-The driver date is 7/21/2014-In device manager|Advanced, U-APSD support is Disbled.-In device manager|Power Management, "Allow the computer to turn off this device to save power" is checked. Hope this helps somebody else.

E7 Nokia Messaging not working after anna update

hi
nokia messaging not working after anna update. when i
-choose provider (hotmail/gmail/yahoo...etc)
-enter username & password
-click OK to T&C
-get error message: "cannot enable this service on the device"
any ideas?

I'm having a similar issue. It appears to only impact Hotmail accounts. For me though, this happened without updating the OS. The email client is simply failing to connect to the Hotmail interface. Only two possibilities, either Microsoft changed something on the email gateway or Nokia changed something on their end. Either way, it's not working and has been out of commission for the past week. If this is how corporate friends get along, I'd hate to see what happens in a adversarial relationship.

Facebook birthdays not working after ios7 update

Facebook birthdays not working after ios7 update?

Did you always have the same problem or is it new? I always used to be able to get Facebook to work on wifi with no issues for months. I downloaded the new software update for Revolution, and all of a sudden it seems like they blocked the Facebook app somehow unless you're on 4G. It really sux because I can't get into my Zynga games either that are tied to FB! Wish someone at Verizon could be aware of this and fix the problem.
Also, interestingly, when I try to log into the Facebook site with the browser I am directed to an error page. The browser works fine for every other site though. Really seems like there was some kind of block instated that will no longer let you use Facebook on a wifi connection.

Nokia C7 GPS not working after belle update!

Hi everyone, i had a C7, working great till i updated it with symbian belle.
okay here is what i did.
-my GPS was working on symbian anna with maps version 3.06beta
-i updated the phone to symbian belle from symbian anna.
-installed nokia maps 3.06 beta, and replaced the one that came with the update because it had the option of route planning which the installed map did not.
-this was the first time i checked to see if the GPS was working after the update, and it did not work even after i stood in an open field for half an hour.
-i learned that the latest update of nokia maps in fact had route planning, so i used the nokia PC suite to reset the phone software, and then later updated everything that was listed in the software update app.
-my GPS could still not work after i stood in the same damn field for another half an hour.
-now it will just give approximate positions based on the wireless networks, and not give any accurate position, so i cant use it for navigation anymore.
-i tried running the gpsinfoqt app, and it keeps saying searching for a signal, but it never finds one!
Please help me!! if there is any way i could flash the C7 or run a diagnostic or something so atleast i figure what is wrong!

Hi akkudub,
Welcome to Nokia discussions board!
Have you used Nokia Suite for the update?
I advise you to follow the steps below in order to get your GPS fully working again:
1) Uninstall the current version of Nokia Suite that you have.
2) Clean the registry with a registry cleaner.
3) On your PC, go to Start > Run and type %temp% and click on "Run". Delete all Nokia folders from the folder that opens.
4) Download the newest Beta version of Nokia Suite from this link:
http://betalabs.nokia.com/apps/nokia-suite-beta
You will need to sign in to your Nokia account - the same credentials used to log into this forum.
We will appreciate your feedback once you have tried this program!
Once Nokia Suite is installed, please connect your device to it and perform the available updates if any is available. Alternatively please reinstall the current software. Also, click on the Maps tab and download the relevant maps files (Europe, UK etc...)
Let us know how you get on and feel free to post any other questions you may have.

astra2025

Jquery content not working after the updates from firefox

Hi, i've realized that some of my website's banner is not working after the recent updates from firefox, whereas those website's banner is working in google chrome.
Hope there is a solution for this as i'm using the firefox for years and wish this issues can be settle.
The banner URL is http://www.irs.com.my/slider/index.html

SlideDeck has a post on how to resolve this error, caused by a bug in this very old version of their library that you're using. See: [http://www.slidedeck.com/blog/firefox-20-update-and-slidedeck-js-weve-got-you-covered/ Firefox 20 update and SlideDeck.js – we’ve got you covered] for more information. As a Pro customer, you were supposed to get an email notice, but... here you are.
I studied the script before discovering that and found two issues, but there might be more:
(1) slidedeck.jquery.js detects Firefox 20 as Firefox 2 and halts. Note that this regex is the problem:
firefox2:F.match(/firefox\/2/)?true:false
(2) Starting in Firefox 16, the -moz-transform property was unprefixed, that is, you need to use transform for Firefox 16 and later.
