Can anyone make sense out of the following sequence of events (on 4.0, I have to admit)?
1. A lengthy ahd(4) Dump Card State 2. sd0(ahd0:0:0:0): Check Condition on CDB 0x2a ... SENSE KEY: Aborted Command ASC/ASCQ: ASC 0x4d ASCQ 0x19 (ASC 4D is TAGGED OVERLAPPED COMMANDS) 3. ahd0: ahd_timeout ahd0:SCB 0x2 - timed out 4. Another lengthy ahd Dump Card State 5. A message from postfix "fatal: open /etc/postfix/main.cf: no such file or directory" 6. Another Check Condition (with ASC 4D) 7. Another postfix message 8. Another ahd_timout message 9. A third ahd Dump Card State 10. /usr: bad dir ino xxx at offset 0: mangled entry 11. panic: bad dir Both /etc and /usr are on a RAIDframe Level 1 RAID (on sd0 and sd1), so I would have expected some RAIDframe message had there been an error reading some block. After a reboot, sd0 didn't respond fully (i.e. the SCSI BIOS reported the drive model, but not the capacity and one couldn't boot from it) until I pulled out its SCA tray and re-plugged it. After that, the machine came up fine.
