Hi guys.
I'm working with FreeBSD 8.0 current using tinybsd to make a image for
my Soekris 4511 box.
The build image is ok and the system boot up perfect, It detect all
the network cards includin the ath0 that is a 400 mw NMP-8602 PLUS.
In the moment that I do :
ifconfig wlan create wlandev ath0
ifconfig wlan up
I'm reciving this :
interrupt storm detected on "irq11:"; throttling interrupt source
and is only when I take up the wlan0 interface, if I don't do anything
with the ath0 card, the system works perfect.
I search in the net for an info and I found a lot of information about
how to build FreeBSD in Soekris boxes, kernel conf files, etc, but
nothing about this caind of problem in version 8.0.
My vmstat -i is :
tinybsd# vmstat -i
interrupt total rate
irq0: clk 170695 490
irq4: sio0 1993 5
irq8: rtc 43697 125
irq9: sis1 392 1
irq11: ath0 32626 93
irq14: ata0 16261 46
Total 265664 763
my pciconf -lv is :
tinybsd# pciconf -lv

My dmesg with ath part :
ath0: <Atheros 5212> mem 0xa0010000-0xa001ffff irq 11 at device 16.0
on pci0
ath0: [ITHREAD]
ath0: WARNING: using obsoleted if_watchdog interface

sis0: Silicon Revision: DP83816A
I can send more information if is needed.
I already change the wireless card ( I have for of the same) and the
matherboard, I upgrade the bios of the Soekris board to 1.38.
Any ideas about the irq storm ?
any special configurations ?
Thanks in advance.
Jose Amengual.
