Hi all,
just to give some feedback on the 3.17 testing proposal: I'm also
affected by the bug reported here (no kvm, both with old and updated
BIOS) for 3.16.x utopic kernels, the problem appeared after short
uptimes of usually 1..2 day.
Now I'm running a 3.17 kernel without a crash for 14 days.
You may also want to try the latest Utopic updates as well.

@Chris - I'm not an expert at reading kernel stack traces, but I don't
think the oops stacktrace looks related to kvm. I just mentioned that I
was using kvm when the oops occurred (*). I've edited the title
accordingly.
(*) - I know this since I have a script which warns me as soon as an
oops is
Hi, can you explain why you think this bug is related to KVM?
From the backtrace it looks like an intel graphics issue.
Thanks
