Hello,
I've tried to upgrade my Linux boxes to 2.6.13.2, and on some configurations
I have problems that IRQ stopped working or devices are not visible on
the PCI bus. These problems may be completely unrelated, though:

between lspci on 2.6.13.2 and 2.6.11.10

Case 2: ASUS A7V600 Athlon box (I have six of those boxes, and the problem
is only on one of them): During boot the IDE controller complains
about IRQ probe failing:

[...]
The pci=usepirqmask boot option seems to fix the problem.
The only difference in "lspci -vv" between 2.6.12.3 and 2.6.13.2
is the following line in the IDE controller section:
- Interrupt: pin A routed to IRQ 14
+ Interrupt: pin A routed to IRQ 11
(altough according to /proc/interrupts, ide uses IRQ 14/15 as usual both
on 2.6.12.3 and 2.6.12.2).
-------------------------------------------------------------------------
Case 3: ASUS A7V8X Athlon box (again, I have six of those boxes, only
one of them does not work): During boot the tg3 NIC is detected,
but does not work (probably no interrupts comming through).
The relevant part of dmesg(8) is
PCI: Using IRQ router VIA [1106/3177] at 0000:00:11.0

Here the pci=usepirqmask does not fix the problem.
Thanks for any solution!
