[Patch] bug in gdth.c crashing machine

[Joerg Dorchain]

Hello Achim,

wrt to your mail to the lkml from 13 Oct 2006 Message-ID:
<EF6AF37986D67948AD48624A3E5D93AFE72291@xxxxxxxxxxxxxxxxxxxx>,
I'd be pleased if you could integrate the derived patch into a bugfix
release of the driver asap.

This bug kept me busy for three days, endangering  backup to tapes.

Patch is against vanilla 2.6.20.

Kind regards,

Joerg
