ncr810 problem on powerstack

ncr810 problem on powerstack

[Alois Fertl]

[-- Attachment #1: Type: text/plain, Size: 244 bytes --]

I tried the recent 2.4.1-pre1 kernel on a powerstack but the ncr810 based
SCSI code does not work. The driver complains about CACHE INCORRECTLY CONFIGURED.

Anybody knows what this comes from. Attached if the full boot log of the system.

Arrrgh, the same thing happens on my powerstack.
I'd track this down, but

a) I don't have time
b) the machine is my mail server and runs the linuxppc_2_2 tree happily.

I saw a similar thing on my LongTrail (with '875 card) after I added a call to
pci_assign_unassigned_resources() to arch/ppc/kernel/pci.c (like PReP) did, and
before I fixed the test for ppc_md.pcibios_enable_device_hook.

Perhaps PReP doesn't like ppc_md.pcibios_enable_device_hook instead of
pci_assign_unassigned_resources?

The recent code in prep_pci.c no longer tweaks pci memory resources to fit
into a 256 MByte BAT range. For some reason this is now limited I/O resources.
I don't know why this change was introduced. The attached diff keeps the handling
for I/O and introduces a similar fix for memory. I don't know if this is the
way to do it. The ncr810 controller starts working again.

  Alois
