Re: Re: Re: i810 Audio driver=disabled

[Jean-Alexander Mueller <jeanm@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Problem was: ... ASUS M2N Notebook ... I810_audio module did not get an 
IRQ and thus, is disabled.

I tried Kernel 2.4.21 and 2.4.20-18.9 with ACPI compiled in (and APM 
out), but that did not help. I ran into more problems, as my USB mouse 
was not detected a.s.o., thus switched back to the RH provided 2.4.20-18.9.
I believe that the problem results from the ICH-4 controler 
module/driver. DMESG shows:
...
ICH4: chipset revision 3
ICH4: not 100% native mode: will probe irqs later
...
As fas as I know, ICH-4 includes IDE-controler, USB, Sound and other 
modules. Thus, if IRQs not probed properly, maybe sound was droped, 
while f.i. USB got one.
A piece of circumstantial evidence - IMHO - could be in the IRQ 
assignments posted already:
  5:       1508          XT-PIC  usb-uhci, usb-uhci, usb-uhci, 
ohci1394, eth0
Why share USB, FireWire and Eth0 the same IRQ ... while IRQ 9..11 are 
free at least?

Any ideas?
