OK. I include an experimental patch for 2.1.86 drivers/scsi/hosts.c
which is applying it. Please test it and send me your comments.
At present I have no possibility to test it with anything more than ppa

So anybody who could test it with more than one scsi host
(especially as modules - which are being removed and loaded again) is
welcome.
With regards
