SubjectRe: Athlon PSE/AGP Bug
From
Date
On the same note.  Anyone trying to run their ram faster than it should
go from the bios would eventually see these kind of things happen. I
used to get errors from anything really memory intensive, games and such
from having ram set at cas 2 instead of cas 3 and removing certain
delays when i shouldn't. People should really make sure their tuned up
systems aren't just overtuned before forking up segfaults to the Athlon
bug that apparently all the kernel guru's have decided doesn't affect
linux just as it doesn't affect the bsd people.

It seems to me that the bug "could" be in your chip, it doesn't mean
it's in every athlon... otherwise we'd be seeing some commonalities and
so far i've seen none.

Since all the people having problems in linux with the athlon bug are
heavy graphics/game users ...I'd suspect overtuning as the problem
before anything else first and make sure they run memtest86, even if
disabling pentium ops fixes things.
