Subject:  [BUG?] GDTH driver not working after upgrade to 2.6.24

Hi,

so i have upgraded a system to kernel 2.6.24. After that, it failed to 
boot with the usual message telling, that the rootfs on device /dev/sda1 
  cannot be mounted (a raid1 run by the controller below).

With 2.6.23.12, everything is working fine.

# lspci -v:

         Subsystem: Intel Corporation Unknown device 01db
         Flags: bus master, 66MHz, slow devsel, latency 64, IRQ 17

         [virtual] Expansion ROM at deef0000 [disabled] [size=32K]
         Capabilities: [80] Power Management version 2

# GDT-related dmesg output (2.6.23.12):

# cat /boot/config-2.6.24 |grep GDT

CONFIG_SCSI_GDTH=y

Any ideas?

http://www.kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%2Fv2.6%2Fpatch-2.6.24.bz2 
show huge drivers/scsi/gdth* related changes.

Can't test at the moment. System went production.

Regards,
   Sven
