Bug#410026: kernel BUG at mm/slab.c:595!
My kernel showed a some kind of bug again, and again it's somehow
related to Iceweasel. I had flash animations going on web page (evil
proprietary flash player). This time I was able to kill the firefox-bin
process and start Iceweasel again: it seems to be working fine, no need
to reboot. A syslog excerpt attached.
