Hello all,

I've taking email addresses from the last NCQ blacklist changes going

This Fujitsu drive also gives me spurious command completions. Detailed
output also available at https://bugzilla.redhat.com/show_bug.cgi?id=366181.

Let me know if you need more info or anything else.

Thanks. We're currently trying to find out what's actually going on
with all these drives. At first, drives which got blacklisted aren't
many and made sense (had other problems with NCQ, etc..) but with new
generation drives from many vendors showing the same symptom, we aren't
too sure now.

I'll keep your email in my todo list and add the drive to the blacklist
once the problem is verified.

I agree that something seems fishy with this. It seems unlikely that this many drives from multiple vendors would have the exact same, relatively obscure problem..
