Re: irq numbers
The reason that the IRQ numbers in 2.6.25 look different from
2.6.22 is because "irq compression" is now disabled on i386
for IRQ numbers below 64. The IOAPIC on a 450NX has 64
entries, so what you see now are always the real pin numbers ==
GSI numbers == IRQ numbers, identitiy mapped.
eg. the mylex was on IRQ16, now on IRQ17,
but has been on GSI 17 all along:
< ACPI: PCI Interrupt 0000:01:08.0[A] -> GSI 17 (level, low) -> IRQ 16
---
> ACPI: PCI Interrupt 0000:01:08.0[A] -> GSI 17 (level, low) -> IRQ 17
and the symbios on 58 and the uhci_hcd:usb1 on 54 now show that way:
< ACPI: PCI Interrupt 0000:00:08.0[A] -> GSI 58 (level, low) -> IRQ 21
< ACPI: PCI Interrupt 0000:00:0c.2[D] -> GSI 54 (level, low) -> IRQ 22
---
> ACPI: PCI Interrupt 0000:00:08.0[A] -> GSI 58 (level, low) -> IRQ 58
> ACPI: PCI Interrupt 0000:00:0c.2[D] -> GSI 54 (level, low) -> IRQ 54
But that just obscures the real failure, which is this:
> ACPI: Bus 0000:02 not present in PCI namespace
< ACPI: PCI Interrupt 0000:02:03.0[A] -> GSI 57 (level, low) -> IRQ 19
< ACPI: PCI Interrupt 0000:02:03.1[B] -> GSI 56 (level, low) -> IRQ 20
---
> ACPI: PCI Interrupt 0000:02:03.0[A]: no GSI - using IRQ 11
> ACPI: PCI Interrupt 0000:02:03.1[B]: no GSI - using IRQ 11
and your 2nd ethernet is on bus 2 and thus died also:
ACPI: Unable to derive IRQ for device 0000:02:01.0
ACPI: PCI Interrupt 0000:02:01.0[A]: no GSI - using IRQ 11
3c59x: Donald Becker and others.
0000:02:01.0: 3Com PCI 3c980C Python-T at f881c000.
