Problem Description:
I'm not sure when this started, but it has been happening (at least)
for the last week, I regularly pull git. I just haven't had the time
to record this oops output until now, and I had to use the
hand-and-paper method. I did try to verify as well as possible. Also,
I ran fsck to fix errors
on this disk in the last week, but it appears the problem still exists.
It does happen often, but I haven't happened to have netconsole on
when it happens. Also S3 does work on this laptop and I use it often,
although I'm not sure that's any help.
I'm not sure when I changed to XFS (within the last two months) and
I'm also not sure when this appeared to start happening :/ This
problem does corrupt whatever I was last working on (usually source
files, it makes them into binaries, at least until I fsck)
I also have no way to just 'reproduce' this. After staying on this box for a
while sometimes it will happen.
