Comment 1 Rafael J. Wysocki 2007-11-04 05:17:15 UTC 
Two patches are available:

http://lkml.org/lkml/2007/11/4/32
http://lkml.org/lkml/2007/11/4/37
Comment 2 Stefan Richter 2007-11-04 05:24:18 UTC 
Patch http://lkml.org/lkml/2007/11/4/37 is unrelated to the bug and not yet necessary (since sbp2 doesn't activate chained s/g lists in its scsi_host_template).

I will push patch http://lkml.org/lkml/2007/11/4/32 to Linus soon.
