MSI K8D Master-3FS with dual Opteron 242 and 8G RAM
AHA 29160 SCSI card
2 bge (BroadCom) on board
>Description:
We run a extremely heavy load service that crashes often with kernel panic
"pmap_invalidate_page". More than ten thousand processes ran simultaneously.
The hardware should be no problem because we test on many boards and different
memory.

How can I help you to debug? Thanks!
