Hi, Is this bug reproducable? If it is, I see in bug 4329 that you've tried switching to http://git.linuxtv.org/media_build.git does it still happen there? This may be related to the locking fix I've done recently: http://git.linuxtv.org/media_tree.git/commitdiff/ceede9fa8939e40ad0ddb4ad1355f45c6f1d3478 But TBH I don't think it is. Although I don't really have a clue if it is not that, then what has caused this backtrace... Also notice that backporting that locking fix to anything before 3.5 is non trivial as it depends on a couple of v4l2-core features which are new in 3.5. Regards, Hans I did not test reproducibility yet. We did make progress in https://bugzilla.kernel.org/show_bug.cgi?id=43291 Tomorrow I can see if that also influences the behaviour for this bug. |
