Well, that's the whole story: in fact using ub driver with your patch applied
i can avoid oops (as said in this thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=109943374727804&w=2)

But the behaviour imho is still buggy and not related to ub driver; it sems
that something goes wrong before ub; in fact I get almost the same behaviour
without ub compiled in, scsi fails in the (quite) the same way, it seems that
something is activated twice. Anyway below I've posted the full syslog
cut&paste, with some comments.
in short: inserting and removing the device causes some errors (maybe
timeouts?) for some tries, (first part of logs) then suddenly, after 3/4
tries, the device is identified and then scsi layer gets activated (and
confused). this time, the removal of device causes a kernel oops. After, you
can also find the behavoiur with ub: no oopses, but the operation is not
complete. I've also tried to turn on the box with key inserted, but I'm
unable to report because the keyboard/mouse (ps/2) was dead, so maybe
something has gone wrong...but i can't tell what. Maybe I can try with serial
console to pickup some messages. Anyway, the key is perfectly working on
first try with another HW and with 2.6.8.1. I've also attached config.gz.
I've checked also config but I can't find something wrong or misconfigured.

anyway, if more infos (or test) are needed, just let me know.

Many thanks.
