You don't mention details on mobo/ram, but if you have >4gb ram on
amd64, you might want to try reducing ram to <=3D4gb. I had one mobo
(Intel DG965RYCK) that was exhibited odd behaviour with more than 4gb
ram installed. Simple file copies (on ZFS), buildworlds etc caused
various panics or outright hangs (!). Usually this would be a clear
indication of faulty RAM, but it passed all memtests. Changed
everything (ram, psu, hdd, cables, RMA'd the mobo), no difference.
Turned out to be a BIOS bug, some linux list had discussions on the
same bug.
