Hi Vlastimil,

Thank you for having provided the above information. The root cause of 
the hang is not yet clear to me. I was wondering whether the hang 
perhaps would be triggered by controllers that only support queue depth 
1. However, in the above output I see "depth 32".

As already reported in this email thread a revert for commit 
88f1669019bd62b3 has been posted on the linux-scsi mailing list. 
Additionally, Greg KH has been asked to drop that patch from the stable 
trees.

Thanks,

Bart.
