AMD SAID THERE IS A LINUX KERNEL BUG related to cache attribute conflicts in newer versions of the Athlon XP and Athlon MP and has appealed to the Linux Community to help it solve the problem.
A posting reveals that the problem is related to the use of the AGP Aperture with Athlon processors but there appear to be short term fixes and long term fixes en route.
A note from Richard Brunner at AMD outlines the problems which happen mostly when an AGP card is present.
But Brunner says that there's a simple short term solution to the problems without major fixes needing implementation in the Linux kernel.
There's already a kernel patch available although Brunner points out there's still a hole left using this short term fix.
As far as the long term solution is concerned, AMD also provides an experimental patch to fix the problem.
