kern/91410: [ata] Promise SATA controller + striping : "SETFEATURES SET TRANSFER MODE semaphore timeout"

[John McLaughlin]

Hi all,

	Belated update on this one, as I finally got back to trying all Søren's
suggestions.

	I tried the suggestion of disabling PREEMPTION in the kernel, and going
down the GEOM route again. No joy though, the system hung again with the
semaphore timeout, albeit after a slightly longer period and heavier
load.

	Using atacontrol to create the stripe has however worked well. I hadn't
RTFM closely enough and had therefore ignored the "Hardware RAID"
section in the handbook as I'd only been considering the card as a non
RAID controller. It's proved rock solid and performs well under heavy
load so this'll be my solution.

	Thanks for the help!

John
