While building a kernel for a Dual Athlon MP 2800 system, I accidentally
enabled CONFIG_NUMA, "Numa Memory Allocation Support". This option should
have been a no-op on the system I was using it on, since on this motherboard
all system memory is equally close to each of the two CPU's. Instead, it
caused userspace processes to randomly segfault.
Booting a 2.6.0 rebuilt without CONFIG_NUMA made the problem go away.

Can you try 2.6.1 with Andi's latest patchset from here:
ftp://ftp.x86-64.org/pub/linux/v2.6/x86_64-2.6.1-2.bz2
There's been quite a few updates to AMD oustanding since before 2.6.0
that Andi said were critical.
If it's still bust, could you fish around in /var/log/messages or consoles
for any stack traces or anything you can see?
