Bug Description

I've recently updated to the kernel 3.13.0-37 from the main repository and got this issue again (I had similar issue before with 3.11.0-15, see Bug #1265971). I tried to update to 3.13.0-38 from ppa:canonical-kernel-team/ppa, but the issue remains.

I'm not sure, but suspect that it's related to my SanDisk SSD U100 drive, another my notebook upgraded without any problem.

I'm reportin this bug booting from the previous kernel, so automatically gathered kernel version info isn't actual.

It's good that fixes the issue. That version will make it into Trusty through the normal stable update process. Can you also test the latest kernel in -proposed, which is -38? It currently has the upstream kernel.

See for documentation how to enable and use -proposed.

Strangely for me, when I re-installed kernel packages from -proposed above the same versions from ppa:canonical-kernel-team/ppa, they do work (I rebooted system several times hot and cold):

Results from ppa were BSOD screenshots attached in comments #2 and #3.

That may indicate that the fix for this has already made it's way into the -proposed repository.

The same issue again with new kernel from repository (3.13.0-39-generic #66-Ubuntu). See attachment above.

This one works:

Please provide me with a list of kernels I should try, if you think it may help.

Just encountered this bug for the first time on latest kernel 3.13.0-45-generic; booting 3.13.0-44-generic works. System is running as a guest inside VMWare Workstation 11.

Well, just for information, 3.13.0-45-generic works fine for me (and 3.13.0-44 wasn't):

Does this bug still affect any of you?

If so, what happens if you remove the quiet option from GRUB?

Nikolay Turpitko (nikolay-w) wrote :

No, I've updated several times since then, all updates went smooth.
I'm on 3.13.0-57-generic now and it also works fine.
Probably, it's safe to close this bug.
