Your interrupt routing table looks pretty strange to me.  I'd try:


and see how that works.  Maybe try different values in place of 11.
The thing I don't understand is why your dump_pirq output shows all
PCI interrupt pins as "unrouted":

> Interrupt router at 00:12.0: Intel 82371AB PIIX4/PIIX4E PCI-to-ISA bridge
>   PIRQ1 (link 0x60): unrouted
>   PIRQ2 (link 0x61): unrouted
>   PIRQ3 (link 0x62): unrouted
>   PIRQ4 (link 0x63): unrouted
>   Serial IRQ: [disabled] [quiet] [frame=21] [pulse=4]

This makes me think my suggestion is unlikely to work, because PCI
interrupts are not being routed in a way that I understand.

But this is an SMP box so maybe this is an IO APIC issue, and the
interrupt routing table doesn't apply.  In that case this is over my
head: maybe contact Martin Mares <> and ask him how to figure
out or fix the interrupt assignment for a PCI device on an SMP box
when the BIOS doesn't fill in the PCI interrupt line register.  He may
tell you that this combination won't work with a 2.2 kernel.

Message Administration

This form allows you to delete, move, or copy one or more messages. You can move messages by copying and deleting the original. The action will be applied to the messages you select above and all replies to those selected messages.

If you want to copy or move messages, specify the HyperNews path of a destination forum or message that all messages will be copied or moved to. The destination must already exist, so maybe create it first.

Path of Destination (a Forum or Message): (e.g. "test")

Notify Subscribers at destination

If you want to delete messages (the default), specify that here. If you want to move messages, you need to delete the original messages; placeholders will be left pointing to where they were moved.

Delete Messages

Caution: After deleteing messages (the default), if you have not copied them (i.e. no destination above), then the selected messages are not be recoverable.
