The PCI IRQ map for the old Motorola PowerStackII (Utah) boards was
incorrect, but this breakage wasn't exposed until 2.5, and finally
fixed
until recently by Sebastian Heutling [off-list ref].
       

Yesterday I finally got around to testing it. It seems the patch has
been applied in Linus's tree so I downloaded the latest BK and tried it.

Still does not work for me but this time it's different. Before the
patch SCSI worked fine but PCI NICs caused hangs. Now I can't test PCI
NICs because even the onboard 53c825 SCSI hangs - seems it gets no
interrupts.

It detects the HBA, tries device discovery, gets a timeout, ABORT,
timeout, TARGET RESET, timeout, BUS RESET, timeout, HOST RESET and
there it hangs.

Does it work for anyone else on Powerstack II Pro4000 (Utah)?

     

It does work in 2.6.8 using backported patches (e.g. the debian 2.6.8
kernel). But it doesn't work above that version because of other patches
in arch/ppc/platforms/prep_pci.c and arch/ppc/platforms/prep_setup.c
(made by Tom Rini?). I couldn't find out what exactly is causing this
problem yet (because lack of time and the fact that my Powerstack is
used as a router).
   

Ah, this could well be my fault.  Those patches were to improve support
of IBM RS/6000 PReP boxes.  Do those machines have residual data?  If
so, could anyone who has one send me the contents of /proc/residual?

Also, a full boot log when working and failing would be cool.
 

No, the PowerstackII Pro4000 (Utah) has no residual. I couldn't see 
anything unusal in the bootlogs except that
neither IDE nor SCSI interrupts occour (timeouts for SCSI and lost 
interrupts for IDE). I assume other PCI-devices have a similar problem. 
I will try to extract some bootlogs in the next days but I think they 
won't help.
