If you're using another driver, there may be more problems. Yes I am using the sgen driver. Yes I agree with you about the stability. The hang exists for every permutation of fresh boot, with/without offline and with/without inquiry. I tried to be thorough before running for help.

Can you find out what driver > you're using for /dev/changer? definitely sgen: lrwxrwxrwx 1 root other 24 Mar 18 11:24 /dev/changer -> /dev/scsi/changer/c3t3d0 lrwxrwxrwx 1 root root 58 Jun 2 16:02 /dev/scsi/changer/c3t3d0 -> ../../../devices/pci@1f,4000/pci@2/scsi@5/sgen@3,0:changer I am sticking a few more debug/frintfs in scsi_sun.c but am definitely open to suggestions.
