[Madwifi-users] irq 10: nobody cared (Debug info)

[Jon A. <jan...@ja...>]

I can repeatably produce an irq: nobody cared message with madwifi cvs 
from yesterday evening and (vanilla) kernel 2.6.9. Unfortunately, it's 
both a new kernel (2.6.9 v.s. 2.6.8.1), and new madwifi (2004-11-07 v.s. 
2004-10-25). This is on a Soekris net4501, with a mini-pci card. Not 
sure how to avoid it. I've put debug info below, if that helps... Anyone 
seen this before, or know of a way to fix/avoid it? (I didn't see a 
solution in some previous messages that dealt with the "irq x: nobody 
cared" problem.)

To get the card going:

~ # modprobe ath_pci
~ # modprobe wlan_wep

Tail end of dmesg:
