SiI3112: problemes with shared interrupt line?

SiI3112: problemes with shared interrupt line?

[Per Andreas Buer]

Hi,

we got a machine with a Nforce2 chipset and a SiI3112 SATA controller.
Two Maxtor disks are configured in software raid, level 1. 

The machine is quite stable as long as I keep the raid degraded. If try
to syncronize the array the machines dies within 20 minutes. No message
given.

This has lead med to believe there is a problem with the two drives
sharing interrupt line 11. I guess it is impossible to force ide2 and
ide3 to use different interrupts as both devices are on the same chip.

I am running Linux 2.4.22-ac3.

Has anyone else seen this?

Just about every bug report I have about SI3112 now is on Nforce
chipsets. At the moment however I don't know what the magic connection
is.

There are two issues I know about:

1) Earlier versions of the Asus BIOS would program incorrect timing in the
nForce internal P2P bridge, causing failures with SI3112 under high disk
activity.  This is fixed in rev 1005 of their BIOS or later.

2) PCI interrupts getting put into edge triggered mode when ACPI/APIC are
enabled.  Andrew de Quincey said this should be fixed in 2.4.22, but I
haven't tested it myself (I have ACPI disabled on all my test systems).  I
did verify his patch on 2.6 when he first posted it, and it works.

I am running the latest (1006, I think) ASUS (this is a ASUS A7
something Deluxe motherboard) BIOS revision.

I've tried disabeling APIC - it did not help.

I'll try 2.6.something tomorrow.

Try to disable both ACPI and APIC, it helped in my case.

   I don't know if this comes under the heading of "SiI3112 bugs", but
Adaptec AAR-1210SA still doesn't work for me (and I've seen one other
identical report on LKML in the last fortnight).

   Any attempt to access the drive (Seagate Barracuda V) causes this
to happen:

Sep 22 20:56:00 src@vlad kernel: hda: dma_timer_expiry: dma status == 0x24
Sep 22 20:56:10 src@vlad kernel: hda: DMA interrupt recovery
Sep 22 20:56:10 src@vlad kernel: hda: lost interrupt

   Data does eventually get to/from the drive, but so slowly as to be
unusable.

   Hugo.

You can look at /proc/interrupts and see if any PCI devices have interrupts
in edge triggered mode, if so your system will be unstable unless you
disable ACPI.  If not, disabling ACPI / APIC probably won't help.
