#636: Interrupts problems with the soundcard
------------------------------------------------+---------------------------
Reporter: [EMAIL PROTECTED] | Owner:
Type: defect | Status: new
Priority: major | Milestone: version
0.9.x - progressive release candidate phase
Component: madwifi: driver | Version: trunk
Keywords: interrupts irq conflicts soundcard | Patch_attached: 0
------------------------------------------------+---------------------------
When I start the ath0 interface (ifconfig ath0 up) I get some
really strange messages from the kernel. Something is going
wrong with the interrupts of my wlan card and my soundcard -
although the interrupts are different.
For the impatient, the error is described at item 6.

1 - First of all my equipment:

- debian eth - about 1 month old

- onboard PCI soundcard

The wlan card is running fine even after these messages.
I cannot check whether these messages have some influence on my
soundcard because this systems is quite new and I was not yet able
to get something out of my soundcard - even without trying the
the wlan equipment.
I should mention here that I '''do not''' get these messages when I
remove the module snd_ens1371 before doing the "ifconfig ath0 up".
But I '''do''' get these messages, too, when doing it the other way round:
{{{
- first "ifconfig ath0 up"
- second "modprobe snd_ens1371"
}}}
Ok, that could give the idea that this might be a problem with
the sound module. However I also have an ethernet card (pcmcia)
and activating (ifconfig eth0 up) it does not result in any
problems - whether snd_ens1371 is loaded or not.
Thus I think that the probability is higher
that the error is within the madwifi modules.

Strange - no change!
Despite the messages given above IRQ 5 still is present here.
