I don't know if everyone is seeing this, but yesterday I hit a bug in
hibernate, and filled a bug for it (LP#752870). I would expect hibernate
not working on a lot of amd64 machines since 18.104.22.168 (may be all,
depending by luck of initialized value of mmu_cr4_features var).
Basically, with 22.214.171.124 it crashes consistently right after image is
restored in resume from hibernate on a test machine here with natty
amd64. After fighting a bit with grub2 to get a full picture of the oops,
I went to bisect, and results are on the ticket.
After getting the fault commit, I went to poke at the code and found the
issue, and right after I saw upstream getting a fix today afternoon. As
a response to this, attached goes the cherry picked fix for natty, the
only one currently affected. I confirmed the fix works on my machine.
Please consider applying it. The patch isn't with Cc stable, I'll try to
contact/send this later to stable ML. Also would be good more testers to
confirm the issue, I'm curious about how widespread is this problem.
