Latest working kernel version: none
Earliest failing kernel version: 2.6.28
Distribution: -
Hardware Environment: IBM eServer 206, 3Ghz, Dual CPU, AR5416 802.11abgn
Wireless PCI Adapter (rev 01)
Software Environment: Hostapd 0.6.7
Problem Description: Kernel\System hangs when using the Ath9k Driver in
Accesspoint mode (not knows in managed mode).
If hostapd is started and stopped the system hangs. Also if hostapd is started
and the wifi card is used the system also hangs after some time. So the card is
not usable yet in my configuration.
There are some configurations knows which had the same problems but after
upgrade to 2.6.27.8 the problem was solved. This had probably to do with DMA
issues. Dont know if this problems is DMA related.
I have tried to use the NMI-Watchdog parameter when starting the kernel. But
then also no info on console or log is produced. Only way to get the system
running is to reset.
Several patched for the ath9k card is used. Also known working configs for
hostapd are used. But the system hang still occurs.
I also have tried the latest wireless-testing trunk, this also wont fix my
problem.

-start hostapd.
-connect with a wireless station.
-do some browsing
-system hangs

- start hostapd
