I was running memtest for 10h, no errors found.
But I found out that when mouse starts jumping reloading the iwlagn
module helps. Of course networkmanager restarts my connections, but it
keeps Firefox running and I no longer see Firefox crashes.
I'm now running without iwlagn module and on external Linksys USB wifi
card. System seems stable.
As for BIOS, in fact it is pretty old (1.31 vs newest 1.34). I'll
upgrade it later and post results.
Thanks for the hints.
