Not running either with the NVIDIA driver or with x86-64 on the machine
I'm getting this on, but I get it fairly often (as in: today I've
probably gotten it at least 5-10 times). It seems it's pretty bound by
either high CPU or disk usage, since I've always gotten it while
compiling stuff so far. Although my system doesn't hard lock if I get
this error; I can at least run most commands and ssh into it.

Not sure if everything in the dmesg output is relevant, but one can
never be sure, so I'm pasting the entire one. Flame on if I'm spamming
you ;)

Oh btw. I'm not subscribed to the mailinglist, so if you'd be kind
enough to CC me I'd be grateful.

Hope this helps,
Patrick B�rjesson
