This sounds suspiciously like the problem(s) I'm seeing with my Sony VAIO
and the 2.4.5 and 2.4.6* kernels.  It seems to work with RH 7.1 kernel
(2.4.2+) though....  I did notice some messages about IRQ routing problems,
but I'm not sure if they are really a problem...  Here is a piece of the boot sequence
from the 2.4.2 RH 7.1 kernel, via dmesg:
.....
Via 686a audio driver 1.1.14b
PCI: Found IRQ 10 for device 00:07.5
IRQ routing conflict in pirq table for device 00:07.5
IRQ routing conflict in pirq table for device 00:07.6
PCI: The same IRQ used for device 00:0a.1
PCI: The same IRQ used for device 00:10.0
via82cxxx: timeout while reading AC97 codec (0xAA0000)
.....

The full dmesg output is attached in case that helps.
