So, I have a working installation of OpenWrt, Kamikaze r12987 on my WRT54GS (v1), complete with b43 driver and functional AP mode. Yay so far!
What I have observed though is that if I try to move any bulk (i.e. lots
of) data through the wireless interface, configured with WPA2, softirq
goes through the roof:
CPU: 0% usr 0% sys 0% nice 0% idle 0% io 0% irq 99% softirq
Load average: 2.36 0.78 0.29
PID PPID USER STAT VSZ %MEM %CPU COMMAND
3 2 root RW< 0 0% 57% [ksoftirqd/0]
715 1 root R 3932 13% 19% hostapd -B /var/run/hostapd-wlan0.con
501 1 root S 1968 7% 10% udhcpc -t 0 -i eth0.1 -b -p /var/run/
I enquired on the bcm43xx-dev list about this and they recommended I ask
OpenWrt people about it. My posting can be seen at:
https://lists.berlios.de/pipermail/bcm43xx-dev/2008-October/008257.html
So has anyone else experienced this problem? Any solutions?
Or I'd even be glad to hear from anyone who has a working b43 driver
with WPA (or WPA2) and doesn't experience high softirq load when they
ram bulk data through, even just as a sanity check that it is possible.
Thanx!
