Subject: Problem with SCSI in 2.6.9

Hello,
I have twice now run into a bug where the scsi layer tries to
synchronize the scsi cache on a device that is no longer plugged into
the system. After this, a cat /proc/scsi/scsi hangs my terminal, and the
load average on the machine won't drop below 1.0. It takes roughly a
month for this bug to show up, I back up my system to a firewire drive
every week, and today on the 28th day of uptime I have this in dmesg:
ieee1394: Node changed: 0-01:1023 -> 0-00:1023
ieee1394: Node suspended: ID:BUS[0-00:1023] GUID[0010100500000689]
Synchronizing SCSI cache for disk sda:
Clearly you can see that the scsi layer tries to sync after the fw
device has been unplugged. All this and I even did this before unplugging:
sync;sync;sync;umount /mnt/backup;
This is the second time I have run into this and I belive is related to
post on the LKM:

Please refer to this email (google it) because I believe it is very related.
