Subject: [Patch] bug in gdth.c crashing machine

Hello Achim,

wrt to your mail to the lkml from 13 Oct 2006 Message-ID:
<[email protected]>,
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

Hi Joerg,

You are right, this patch should be added to a bugfix release as soon as
possible.
