Can you try to get a snip of text printed by the SCSI driver?

I seem to be having some issues with the newer SCSI driver
(October merge) on my 715/50's ... I'll post my info tommorow.

In particular (0.9.3 Install with apt-get updates):

Kernel 2.4.16-pa21 (Will be updating tommorow)

- Most of the drives I put into the box refuse to spinup.
	= E.g. "spinning up....." until timeout

- Boxes with 525MB HP Quantum ProDrive HD's lockup solid in
  mke2fs while writing superblocks (always happens).

- Drives that do spinup are reported as 0MB's because the 
  sector size was invalid (4GIG Barracudas)

- Random lockups accessing the drive on 712/50's that 
  seem to have functional drives. Usually manifested as
  a solid lock at a Random time during Init scripts.
  (I know cause I ran init=/bin/sh and straced evertyhing)

Most of our cluster is running 2.4.9-pa25 <= Very Stable.

Mind you, the latest kernel runs fine on our 712/60. 
And since the problem _looks_ to be SCSI related...
that's what I'm going to try investigate.

=-= Help investigating =-=

I'm wondering if I'll need to get kgdb??
Or something other than serial?
The box _locks_ solid, no response, and I'm not quite sure
how to diagnose that.
