kernel failure

Sat Dec 13, 2014 6:17 am

I updated my kernel a few days ago. Everything was running smoothly. Then this just popped up after coming out of suspend:
Kernel failure message 1:

Things seem to still be working OK. Should I be in panic or just ignore it and go on about my business. First time in all my Linux years that this has happened.

If it's reproducible, you could try downgrading to the previous kernel and see if that fixes it.

ls -l /var/cache/apt/archives/linux-image-*.deb
will show you the old package(s) with the dates.

dpkg -i --force-downgrade <old-package>
To install the older version

Thanks for the advice. No error message when I unsuspended this morning possibly because I sent it off to the kernel team?

Only the current kernel is in /apt/archives. So to downgrade I guess I'd have to force the version if the error crops up again or things go sideways.

To force a downgrade, you need to have the deb file. Latest one I have for squeeze is from May of '13. You can probably find the one you want at snapshot.debian.org (or is it snapshots...?) Or at least it's there - finding it might be a challenge.

OK. So far still working and no hiccups. You see the conversation on #devuan between dzz and max2344 this am?
