Subject: irq nobody cared issue on 2.6.2x

hi all,

i just moved my win tv dvb-s card (PCI) from my old to my actual pc.

its an ASUS M2N32 WS Professional AMD64 X2 Board equiped with
the nvidia nForce 590 SLI MCP chipset.

in the past, i had to use the noapic kernel cmdline param to get linux
booting and working properly.

iirc versions >=2.6.18 of the kernel fixed all of my previous problems,
thus i am not using noapic since then.

if you would be so kind to provide me some infos,

how i would be able to track the problem down _and_ maybe how to fix it.

please find two snippets of dmesg after booting 2.6.21-rc3-git 
(2.6.20-1 has got the same results) 

best regards
marcel
