It may be hardware. I reported that one of my servers (running a 
4/22 3.0-current) rebooted without showing a crash in the
logs every one or two days.

After switching on DDB today I caught the machine in a trap:

Fatal trap 12: page fault while in kernel mode

fault= 0xd0336a40
ip= 0x8:0xf01b7d5a
96 (nfsd)

_vm_page_insert + 0x4e:  movl %ecx,0(%edx)
_vm_page_alloc
_allocbuf
_getblk
_clusterread
_ffsread
_nfsvr_read
nfssvc_nfsd
_nfssvc
...(from syscall)

typed (not literally) off screen.

This machine is running a 6GB ccd disk and nfsd/mountd.
It may be heavy loaded from time to time by nfs usage.
Amd K5/PR133, 512 K cache.
2x NCR810 SCSI one 3 GB at each.
