New video card, X server will not start; irqbalance shutdown fails

[Gregory E. Garland]

Hello all,

My previous video card (ATI Radeon 9800 AGP) decided to bite the dust, so I
replaced it with a new ATI Radeon X700 Pro AGP card. Naturally, this card
does not appear in the list for the display configuration tool, and trying
to use any of the other Radeon types that are gives an error of "No Matching
Device Section for instance (BusID PCI:1:0:1) found"; "No devices detected"
and the X server does not start. I can start server using the generic VESA
type, and there does appear to be a relevant article (Article ID: 5642) in
the Red Hat Knowledgebase about installing ATI Drivers on a 64-bit machine
(The PC has an AMD Athlon 64 CPU, and is running Red Hat ES 4). However,
before I install these 32-bit packages and see if that solves the problem I
have noticed that when the machine shuts down there now appears an error
message saying that irqbalance failed to shut down. So I'm wondering if
there is something else going on that causes the system to fail to detect
the new video card.

Thanks for any observations.

Greg
