Dunno if this is of any use, but i have a Toshiba 40?? CD laptop (Satelite)
at work, sorry, can't remember the exact model No.
Its a 400MHz Celeron with 64 megs of ram and about 4 gigs of hard disk,
cd-rom & 800x600 Dual scan display.
I found that with the 2.2.x kernel supplied with redhat 6.1, the machine ran
ok, but on the 2.3.x kernels it would crash at random under heavy load. I
eventually noticed that reguarly one of the registers displayed in the oops
would contain nothing but FFFF's, so i thought i'd try telling the machine
it only had 60 megs of ram to see if that fixed anything, and, sure enough,
running 2.3.99-pre6 with the Lilo append="Mem=60M" line, its not crashed
once.
Maybe you are having the same problem. It showed up when under heavy load,
ie kernel compile or starting loads of big x apps. Worth a try at least ?
