spurious IRQ complaints

2001-01-27 Thread David Ford

PCI: No IRQ known for interrupt pin A of device 01:00.0. Please try
using pci=biosirq.

01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 RF
(prog-if 00 [VGA])
Subsystem: ATI Technologies Inc: Unknown device 0008
Flags: bus master, stepping, 66Mhz, medium devsel, latency 64
Memory at e400 (32-bit, prefetchable) [size=64M]
I/O ports at d000 [size=256]
Memory at e900 (32-bit, non-prefetchable) [size=16K]
Expansion ROM at e800 [disabled] [size=128K]
Capabilities: [50] AGP version 2.0
Capabilities: [5c] Power Management version 1

Does it really need one?

DRI versions of X seem to behave better if an IRQ is assigned to the VGA
device via the BIOS. Didn't seem like a problem to let it have one, so I
did. :o)
