[PATCH] Maxtor 6B250S0/BANC1B70 hangs with NCQ
I've seen this several times on this drive, completely reproducible. Once it has hung, power needs to be cut from the drive to recover it, a simple reboot is not enough. So I'd suggest disabling NCQ on this drive. Signed-off-by: Jens Axboe <jens.axboe@oracle.com> Acked-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
