Bug Description

Hello,

Bug Package : linux-image-3.0.0-14-generic

I found a regression between "Linux 3.0.0-14-generic" and "Linux 3.0.0-13-generic".

I installed linux-image-3.0.0-14-generic on 2011-12-11. I start my computer on 2011-12-12 :
Dec 12 18:21:54 joseph-desktop kernel: [ 20.821145] scsi: killing requests for dead queue
Dec 12 18:21:55 joseph-desktop kernel: [ 21.816786] scsi: killing requests for dead queue
[...]
Dec 12 23:55:32 joseph-desktop kernel: [20040.000936] scsi: killing requests for dead queue
Dec 12 23:55:33 joseph-desktop kernel: [20041.000856] scsi: killing requests for dead queue
Dec 12 23:55:34 joseph-desktop kernel: [20042.000859] scsi: killing requests for dead queue
Dec 12 23:55:35 joseph-desktop kernel: [20043.000888] scsi: killing requests for dead queue

Today, I see this bug (because my computer froze and I have to push my power button to reboot). So i tried to boot on Linux 3.0.0-13-generic kernel. And there is no "scsi: killing requests for dead queue"

@little jo

Would it be possible for you to test some kernels? I'd like to revert the commit I mentioned in my previous comment and see if it fixes your issue.

There is a test kernel available at:
http://people.canonical.com/~jsalisbury/lp918949/

Can you test this kernel and report back if it resolves your issue?

Sorry, I haven't got time to test it yet at this moment. I'll try to do it this weekend.

Thanks for testing. I'll investigate further.

Joseph Salisbury (jsalisbury) wrote :

There is a newer version of the kernel(3.0.0-16.28) than the one you tested when this issue was found. Can you test again with the newer kernel and indicate in the bug if this issue still exists or not. You can upgrade just your kernel by running the following in a terminal:

sudo apt-get update
sudo apt-get install linux

If the bug still exists in the latest kernel, please change the status back to "Confirmed". If the bug is fixed, please change the status to "Fix Released".

Thanks in advance
