[Dri-devel] DRM, i810, IRQ conflict

[Michael Z. <zmi...@po...>]

The configuration is following:

i810 + 2.4.3 + agpgart + 4.1.0 + kmod from 4.1.0

I have the following problem:

when drm loads (from /var/log/XFree86.0.log) it reports that
it can't register IRQ handler due to another device that have taken it.

it's true that lspci shows that both my video card and ethercard use IRQ
11.

2 questions:

1) theoretic: Why at all drm needs IRQ i.e. does AGP sends info back to
the driver?

2) practical: AFAIK BIOS is in charge of setting IRQs, but the only
thing my AWARD bios enables to set for each IRQ is whether it is
Plug-n-Play or Reserved. How do I rearrange PCI cards IRQs?


thank you in advance for any help
