[Linux-ia64] IRQ problems when running McKinley Kernel on Proliant DL590/64

[Linux-ia64] IRQ problems when running McKinley Kernel on Proliant DL590/64

[Stephen Mulcahy]

Hi,

I've been experiencing some problems with some ia64 kernels (both ones
I've gotten in debian and those I've compiled myself) on a Compaq
Proliant DL590/64 which I've been doing some test installing on.

The problem manifests itself with the following error output on
boot-up

PIIX4: IDE controller on PCI bus 00 dev 39
PCI: Found IRQ 0 for device 00:07.1
PIIX4: chipset revision 1
PIIX4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0x1000-0x1007, BIOS settings: hda:pio, hdb:pio
hda: IRQ probe failed (0x7ffffffe)
keyboard: Timeout - AT keyboard not present?(ed)
hda: IRQ probe failed (0x7ffffffe)
hda: CD-224E, ATAPI CD/DVD-ROM drive
hda: IRQ probe failed (0x7ffffffe)
hdb: IRQ probe failed (0x7ffffffe)
hdb: IRQ probe failed (0x7ffffffe)
hdb: LS-120 SLIM6 AG UHD Floppy, ATAPI FLOPPY drive
hdb: IRQ probe failed (0x7ffffffe)
ide0 at 0x1f0-0x1f7,0x3f6 on irq 34
hda: lost interrupt
hda: lost interrupt
hda: ATAPI 24X CD-ROM drive, 128kB Cache
Uniform CD-ROM driver Revision: 3.12
ide-floppy driver 0.97.sv
hdb: lost interrupt
hdb: lost interrupt

I've tried various kernel configurations with a view to isolating this
problem, initially assuming it to be the same problem seen with
some omnibooks where PIIXn autotuning caused lost interrupt
problems due to various errors in drivers. After compiling a number of
kernels, the error only occurs on the system if I compile a kernel for
Itanium-2/McKinley rather than Itanium i.e. I can compile an Itanium
kernel with generic pci bus-master support etc. and don't experience
any of these problems so I assume there are some changes in the
mckinley support which cause or reveal problems in the ide irq
handling stuff.

Sorry for the lack of technical depth on this, I'm not sure what
additional information may of be of use to people in resolving
this. I'll concentrate on compiling kernels for Itanium rather than
McKinley for now (the current debian woody images for ia64 default to
using the mckinley kernel, I'll drop them a note suggesting they may
wish to default to itanium to avoid this problem).

I've seen this on the linux 2.4.17 mckinley smp kernel as distributed
by debian and a number of linux 2.4.18 kernels (with the
latest ia64 patch kit) compiled by myself. I can provide further error
output and kernel config files if they're of use to anyone.

Thanks,

-stephen

   A McKinley flavor kernel actually uses the PCAT Compatible interrupt
flag in the MADT table to determine if a dual-8259 interrupt controller
is present.  The Itanium kernel just assumes it's there because earlier
firmware for Lion did not have the flag set correctly.  For Lion, this
was fixed in fw 99.  I don't know if the DL590/64 is a version of the
Lion or not.  You'll probably want to check if there's newer firmware
available or toggle the ifndef CONFIG_ITANIUM in arch/ia64/kernel/acpi.c
to verify this is the problem.

Hi Alex,

Thanks for your response. I've made some inquiries and this is a known
firmware issue that will be resolved in the next firmware release for
this platform, however the timeframe for this firmware release isn't
decided yet. In the meantime, people wanting to run linux on a dl590
may wish to compile an itanium-specific kernel to avoid interrupt
problems.
