Description Alfredo Ferrari 2001-11-11 14:51:43 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.9-13.1 i686)

Description of problem:
All scsi partitions mounted thru my scsi pcmcia controllers (apa1460 or
apa1480a, the latest using aic7xxx_mod) are not properly unmounted at
shutdown. Actually the system stops the pcmcia services WITHOUT unmounting
the scsi partitions and then hangs with a kernel OOPS... when trying to
unmount all filesystem later.

This is a very bad bug which is there since the "new" kernel based pcmcia
package (yenta_socket) and was never there with the previous pcmcia
modules. Also 7.1 is affected as well. You can easily crash the system at
shutdown time and trash the scsi disks of course.

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

How reproducible:

Steps to Reproduce:
1.mount a scsi partition thru a pcmcia scsi controller using aic7xxx_mod (I
used an Adaptec apa1480a)
2.shutdown the machine without manually unmounting the partition
3.look at the resulting kernel oops

Actual Results:  the machine got a kernel panic

Expected Results:  an orderly done shutdown with proper unmounting of the
relevant partitions BEFORE shutting down the pcmcia services

Additional info:

I have RH7.2 with all updates installed on a Latitude C800 with an Adapted
apa1480a adapter and one scsi hd, one fuijtsu MO drive and one Yamaha CR/W
write attached to the scsi chain. The problem appears on both the hd and
the MO, whichever is mounted, and it was there as well on RH7.1 (I just
upgraded and discovered it was not fixed)

It is nice to see how nasty bugs are solved quickly... of course still there in

Comment 2 Dave Jones 2004-10-26 02:33:23 UTC
going through old unclosed bugs..
Did this ever get resolved? Does this problem still exist
in our current Fedora/RHEL products ?

Please reopen if this is still a problem.
