I have a system with a Tyan 2885 motherboard (S2885-ANRF) that uses dual Opteron 244 processors. Each processor has 1 GB of memory for a total of 2 GB. I am using a SATA HD. I am running the latest stock release of the SMP version of the FC3 kernel for x86_64. uname -a output follows:
Linux maggie 2.6.11-1.14_FC3smp #1 SMP Thu Apr 7 19:36:23 EDT 2005 x86_64 x86_64 x86_64 GNU/Linux
The computer is worldly node for a small cluster of computers. It is resposible for building a code that is run on the cluster. A shell script is used to start the build process. Occasionally when the script is started it crashes and the following messages are place in /var/log/messages (sorry for the ugly line wrap):
May 11 16:26:56 maggie kernel: mm/memory.c:97: bad pmd ffff81002f6a4000(0000000000000008). May 11 16:26:56 maggie kernel: mm/memory.c:97: bad pmd ffff81002f6a4010(0000000000000009).

May 11 16:26:56 maggie kernel: mm/memory.c:97: bad pmd ffff81002f6a4098(000034365f363878).
If the shell script is started immediately after the crash it works. I have been seeing "bad pmd" messages for quite some time and the shell script that builds the code is not the only event that triggers them.
I'm pretty sure the memory in the machine is fine. I have noticed a thread on linux-kernel list discussing the problem, but haven't had a chance to post there yet.
I have appended the output of lspci and lsmod to the end of this message.
Has anyone on this list noticed similar messages?
The linux-kernel thread indicates the problem is x86_64 specific and seems to be hilighted by Tyan HW.
Any insight would be greatly appreciated. Pete
