Subject: Re: ath5k AP kernel panic when client uses SCP
Date: Sun, 11 Oct 2009 19:55:43 +0200 [thread overview]
Message-ID: <4AD21C1F.1090309@wpkg.org> (raw)
In-Reply-To: <4AD21AB4.6010208@wpkg.org>
Added linux-net as I used a wrong address in the original mail.
> I am able to trigger this kernel panic when a client copies data using
> SCP to another client using the same AP:

> client_1 <---wired---> AP <---wireless---> client_2
