pdc202xx_new and ACPI

Hello dear ACPI-ML!

When I boot with 2.6.16.20, acpi enabled and the Promise pdc202xx_new installed, the system 'sleeps' / 'freezes' after recognizing hdi. The message I get is the following:

(damn no serial console, have to copy it by hand....)

--------------------------------------------------------------------------------
irq 10: nobody cared (try booting with the "irpoll" option)

This problem is not really new:

In <[email protected]> on Sun, 5 Dec 2004 01:59:46 +0100 I described a problem regarding this controller:

0000:02:01.0 RAID bus controller: Promise Technology, Inc. PDC20270 (FastTrak100 LP/TX2/TX4) (rev 02)

In <1102286168.2308.13.camel@d845pe> Len Brown gave me the hint to use "acpi=noirq". This works again.

This time the same controller is installed into a different mainboard, cpu, ram (so: another computer).

I would like to debug it this time to the end, so we can figure out where the problem is and how to solve it.

Please CC-me on reply.
