The story of the interaction of the Linux 2.4 kernel, AMD procs, and 
support chipsets continues.  Anyone interested will want to take a look 
at gentoo's latest news on the issue:

A quote from gentoo's news item:

>
The GART and the CPU see two different views of memory, and it's the 
kernel's responsibility to map memory in such a way as to prevent bad 
interactions. Currently, that isn't happening. Third-party drivers such 
as the NVIDIA driver for Linux may also have some problems in this 
area. Now that the Linux kernel development community is aware of the 
issue, they have started the process of devising a good approach to 
avoid this memory corruption problem. Disabling extended paging via the 
mem=nopentium boot option is really not a good long-term solution since 
it can impact performance, so a better solution is needed.
