Thanks, peterbo. Sorry, got confused. Of course, I'm running it on 13.04, too. I have had these really weird crashes before (rebooting by itself) and they went away after one of the kernel upgrades, maybe even when upgrading from 12.10 to 13.04. Got the Hangcheck timer elapsed ones instead. That is, sometimes, when I return to my laptop, it is turned off even when I'm pretty sure I left it on, so maybe they have just been happening while idle. Now with the rc5 kernel I got the original crash (without error log) within hours again, so I got discouraged from trying any further. It's my work laptop, running dual monitors, and I really can't afford to experiment too much as I need it to run and do its job. I still can't believe that this is such a persistent bug (several bugs?). The Linux kernel used to be considered bomb-proof! Apparently its bugs, too...
