Just in case any one missed it... These is a hardware bug in the Athlon processor's extended paging (PSE) that cause serious problems when AGP is in use. I've attached a copy of the article as the site is currently slashdotted.

"The bad news is that a major Athlon CPU bug has been discovered, and it affects Linux 2.4. Note that this is a bug in the actual CPU itself, and is not a Linux bug. However, it becomes our problem because there are very many semi-broken Athlon/Duron/Athlon MP CPUs out there.

Sorry,

it is not true that Linux 2.4 is "hard" affected. Read L-KML about it. http://marc.theaimsgroup.com/?l=linux-kernel&m=101168170221868&w=2

Linux "only" use aligned access of 4MB pages, but the current Nvidia kernel module seems to be affected.
