2.6.5: Hitachi HA8000/70 panic, missing devices

[Charles Duffy <charlesduffy-doANK8/0m3qakBO8gow8eQ@public.gmane.org>]

Howdy. I'm presently working with a Hitachi HA8000/70. This system has a
Gigabyte motherboard primarily using ServerWorks chipsets.

With ACPI fully enabled, the system boots but fails to recognize some
PCI devices. Booting with pci=noacpi, or with ACPI deselected but
ACPI_BOOT selected, the system panics. This happens in SMP or UP as long
as ACPI_BOOT is enabled.

I'm able to convince the system to boot correctly (and show all devices)
in uniprocessor mode with PCI_GODIRECT and ACPI (as well as ACPI_BOOT)
disabled. The system was able to boot correctly running SMP in 2.4.



I've included links to a wide array of potentially relevant information
below. If there's anything I've left out, or some test I could run,
please let me know. If you're really interested in this one and in the
Austin area, it may be possible to loan the hardware or get together in
person -- I'll buy lunch.

A hand-typed boot log (no null-modem cable available) showing the panic
with pci=noacpi is at:

dmidecode output is at:
http://quackerhead.com/~duff/HA8000_70/dmidecode.txt

The original ACPI DSDT is at:

My modified ACPI DSDT (same issue; less dead code and IASL-friendly):
http://quackerhead.com/~duff/HA8000_70/dsdt.new

Extra-verbose lspci output with a uniprocessor, non-ACPI_BOOT kernel:
http://quackerhead.com/~duff/HA8000_70/lspci_direct_pci_config.txt
the above shows all devices in the system.

Extra-verbose lspci output with a fully ACPI kernel:
http://quackerhead.com/~duff/HA8000_70/lspci_full_acpi_config.txt
the above is missing the GigE and SCSI controllers.

/proc/interrupts with the SMP ACPI kernel (and missing devices):
http://quackerhead.com/~duff/HA8000_70/interrupts_full_acpi_config.txt
this one uses IO-APIC-{edge,level} almost everywhere

/proc/interrupts with the UP non-ACPI kernel:
http://quackerhead.com/~duff/HA8000_70/interrupts_direct_pci_config.txt
this one uses XT-PIC everywhere

dmesg output with the SMP ACPI kernel (including ACPI debug info):
http://quackerhead.com/~duff/HA8000_70/dmesg_full_acpi_config.txt
