Hello List,


I recently upgraded my laptop, HP Pavilion N5430, from a 2.4.21 kernel
to 2.6.12. As a result of
doing this my sound no longer works correctly. It plays the same thing
repeatedly some number
of times - if it plays at all.

Any ideas on how to debug this would be appreciated.

Additional info I don't see any interrupts in /proc/interrupts for the
Allegro which is on int 5.
I just tried the same laptop with knoppix and a 2.4.27 kernel and sound
works great and I do
see interrupts for Allegro on int 5.



The irq problem is likely related with ACPI.
Try to boot once with pci=noacpi.

Hi Takashi,

I have boot the 2.6.12 kernel with acpi=off pci=noacpi,usepirqmask or I
get a panic or a hang.

I don't have to do this with 2.4.27, anybody know why?
