Message-ID: <4C677231.5050709@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org 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.
