Panic is confirmed. This time, it lived long enough to log:
May 6 14:05:05 babylon5 kernel: Kernel panic: scsi_free:Bad offset
Since it involves the CDROM, the aha1542 driver is implicated. Why it's getting a bad offset, I don't understand enough about the SCSI drivers to know; all the scsi_free calls in aha1542.c look identical to me.
Would any Linux SCSI gurus care to let me know any diagnostic procedures recommended for nailing this one?
