Subject: 2.6.23-rc4-mm1: deadlock while mmaping video device
Date: Thu, 13 Sep 2007 13:43:43 +0200	[thread overview]
Message-ID: <46E9226F.9010700@gmail.com> (raw)

Hi,

I have this circular lock dependency on 2.6.23-rc4-mm1 when opening
/dev/video0 and mmaping it. the v4l driver is stk11xx:

Using slub on x86_64 if that matters.

For now, I'm unable to set up a netconsole, so only the picture linked above
is the best I have.

regards,
