smp memory problem

Hello All,

I have the following problem. I have a feeling that there is kernel bug
related to memory access.

By the way parallel to this i'm also looking for tests, to see wither
there is a hardware problem. I already did memory test for several hours.
No problems found. I have a tiger s2460 mainload with 2 thouroughbred A
1800+ processors on it.

This is the error i get:

EDAC MC0: UE page 0x0, offset 0x0, grain 536870912, row 0, labels "": AMD762
Kernel panic - not syncing: EDAC MC0: UE page 0x0, offset 0x0, grain
536870912, row 0, labels "": AMD762

REMARK: I typed this over from the screen. So there might be typos in it.
I have a digital foto of the screen. If needed i can send it. You
sertainly don't want it on the mailing list.
