I'm using the latest linus git tree. This is in fileio mode with

logout? Thanks!

I think that the fix is in Mike's iscsi git tree.
Yeah, we used to remove the devices from userspace as a workaround, but
in 2.6.21 doing
echo 1 > /sys/block/sdc/device/delete
changed behavior from where it used to not return until the delete was
done to where it returns right away.
In my iscsi git tree I finally fixed up the iscsi shutdown code so we do
not encounter this problem. We did not notice the problem until,
recently and the fix is larger than what people probably want for stable
kernels the so it should hopefully make the next 2.6 kernel.
