Description Keith Hopkins 2002-05-21 02:42:52 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020408

Description of problem:
During shutdown, the system panics after the pcmcia script unloads the aic7xxx
module.  The aic7xxx module is driving a pcmcia scsi card, and there are mounted
file systems on a external hard drive attached to that card.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
prereq: pcmcia scsi interface card, external scsi drives with usable file system.
1.mount a file system from external scsi hard drive attached to pcmcia scsi card.
2.execute "shutdown -hy now"
3.pcmcia script unloads pcmcia scsi module with file systems still mounted
4.system on fire! (kidding, system panics and hangs)

Actual Results:  panic/hang with root and other file systems still mounted.

Expected Results:  file systems on external device should be unmounted before
the driver is unloaded.

Additional info:

Manually umount'ing the file systems on the external scsi drive before running
shutdown allows the system to shutdown normally.

ok this is indeed rather unfunny. investigating.
Comment 2 Arjan van de Ven 2002-05-22 07:34:32 EDT
quick question: is it pcmcia or cardbus ?
Comment 3 Keith Hopkins 2002-05-23 22:47:53 EDT
The Adaptec product is labeled "CardBus" on the front
