I have a brand new Tyan k8sr based system with a megaraid 320-2X controller in it. This is my second copy of this box (the first one is being replaced since it keeps locking up and reporting "memory size changed" in the BIOS, even with a new motherboard)... Anynow, this particular machine has just simply locked up with no errors reported to console or syslog or BIOS. It does have a newer BIOS rev, so perhaps that is why nothing is logged to BIOS... This happens during times of heavy loads (large database reports, database dump, database replication all simultaneously running). If the machine doesn't crash, I'll see a "bge0 timeout -- resetting" in the syslog most days during the time of heavy load (reports run on a remote client). I see at http://unix.derkeiler.com/Mailing-Lists/FreeBSD/hackers/2005-03/ 0419.html that this is happening to at least one other person on this motherboard, but using the on-board controller. Someone else just noted similar lockups with 5.3 with SMP running mysql, and about 2 weeks ago there was a discussion about amr driver panic under 5.4-PRERELEASE, both on the stable@ list. However these were not amd64 systems, if that matters. FreeBSD 5.4-PRERELEASE as of March 22, 2005 is running on this system. It has a dual Opteron 246 2GHz and 4GB RAM. Could it be some strange interaction of the K8SR and the 320-2X megaraid card? This makes two machines exhibiting very unstable behavior, and I've already replaced the motherboard on one of them.
