Message-ID: <5097936C.2040205@googlemail.com> Date: Mon, 05 Nov 2012 10:22:36 +0000 From: Chris Clayton <chris2553@...glemail.com> To: LKML <linux-kernel@...r.kernel.org> Subject: linux-3.7.0-rc3+: Warning found in log files Hi, Whilst browsing the log file on my laptop (looking for diagnostics for a problem I have resuming from a suspend to disc), I spotted the warning below. I see that vlc is mentioned. I did have a problem yesterday when, through vlc's UPNP functionality, I was unable to play a video stored on my NAS. I can't be sure whether that is related to this warning because I parked it and got on with investigating my resume problem. I've had few goes at playing the video this morning and I still can't get it to play via upnp, but the warning hasn't appeared, so this may be a read herring.
