>Description:
trm(4) is not in GENERIC. Loading it causes a panic on my Ultra 10:

# kldload trm
trm0: <Tekram DC395U/UW/F DC315/U Fast20 Wide SCSI Adapter> port 0x400-0x4ff mem 0x2000-0x2fff at device 1.0 on pci2
panic: trap: data access error


The same thing happens if trm.ko is loaded at boot time.
