G'day all,
I've got a box here based on current Debian Stable.
It's got 15 Maxtor SATA drives in it on 4 Promise TX4 controllers.
Using kernel 2.6.21.x it shuts down, but of course with a huge "clack" as 15 drives all do emergency
head parks simultaneously. I thought I'd upgrade to 2.6.22-rc to get around this but the machine
just hangs up hard apparently trying to sync cache on a drive.
I've run this process manually, so I know it is being performed properly.
Prior to shutdown, all nfsd processes are stopped, filesystems unmounted and md arrays stopped.
/proc/mdstat shows
root@storage1:~# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
unused devices: <none>
root@storage1:~#
Here is the final hangup.

They keyboard is responsive up until the "hard resetting port" when it just locks solid and requires
a power-cycle.
It's not really something I want to bisect if I can avoid it give the lovely noise it makes when I
power it off. (this box only has a hard power switch, no reset or soft power buttons)
