Intel 6300ESB SATA - Now Tyan B5350G20S2H-LC

I've had simular issues with an Asus PCH-DR motherboard: it would crash
with BTX errors upon install with a recent FreeBSD version, hang at very
odd intervals etc.

turned out that the raid bios (Promise) was the culprit. once
I removed all SATA drives from it (which caused the RAID BIOS not to
install itself), the box had no issues and did 100+ days of uptime until
a power failure caused it to reboot... :(

It may be a long shot (as this is a completely different motherboard)
but it may be worth a try, as you seem to use the on-board RAID as well.
