[ath9k-devel] crash in ath9k driver ?

[burlen]

Hi,

I have some problem with wifi on my laptop with chip:

03:00.0 Network controller: Atheros Communications Inc. AR928X Wireless 
Network Adapter (PCI-Express) (rev 01)

kernel

Linux g50vt 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC 
2010 x86_64 GNU/Linux

dmesg shows a crash, looks like ath9k, occurred during startup, and I 
can't connect to any wifi. Details follow.  Is this a bug in ath9k 
driver? Any idea how I can work around? I am stuck with this kernel 
because this laptop has dmraid raid 0, and kernel is held back during 
updates.

Thanks
Burlen
