>Description:
When running the mount command on the ATA CDROM device /dev/cd0, the mount process (cd9660) hangs indefinitely.  It cannot be killed with a kill -9 signal.  Fails with a plextor ATA CDROM drive in its place too so it's a controller/os/bus issue.

The hardware is the same as a compaq proliant 850r except in desktop form. See dmesg for details.

Only a reboot solves the problem as the process is unkillable.

MEdia and drive work ok in another system.

Might be something to do with: ?

acd0: MODE_SENSE_BIG command timeout - resetting
ata0: resetting devices .. done
acd0: read data overrun 10/0
acd0: read data overrun 4/0
acd0: CDROM <HITACHI CDR-7930> at ata0-master PIO3
>How-To-Repeat:
# mount /cdrom

.. process hangs and never completes.
>Fix:
Unknown apart from use a SCSI CDROM.
