So how do you know that you "no longer" can use USB sticks if you
did not find a kernel where it worked? It's either one or the other.

Middle huh. I _really_ wish people stopped editing their logs. How
am I supposed to determine if this was sent immediately after open
(e.g. your HAL is screwing with you), or it happened after a time
of inactivity?

In the latter case you might try to comment out
sdev->allow_restart = 1  from scsiglue.c.
It was added there for a specific reason: Seagate FreeAgent.
We can easily make it specific for Seagate, *IF* commenting it helps.

In the former case, well, complain to distro.

GOD, NO. We went down that road before.

P.S. If userland were sending these commands, ub would fail too.
So it's not a heaven from this problem.
