Let me preference this by saying ... I am not a kernel programmer :)

But, it seems to me that the issue that you have is caused by 1 of 2
components...

Either the 3w_xxxx driver module ... or the ACPI module and power saving.

To try and fix this I would try the following:

1.  Make sure you have the latest BIOS for the motherboard (new BIOSes
frequently update the ACPI code for the board).

2.  Make sure you have the latest BIOS for the RAID controller card.

3.  Turn off / disable all power saving features in the BIOS.

4.  See if the RAID manufacturer provides a driver for the RAID that is
newer than the one provided by the 2.6 kernel.

If it still happens, add this to your kernel line:

 acpi=HT

(this will turn off several ACPI features, but still let the machine power
off)

5.  If that doesn't work, try this on the kernel line (instead of acpi=HT):

 noacpi
