Subject: TBS6981/vb2-cx23885 kernel oops
Date: Wed, 28 Jan 2015 12:01:02 +0000	[thread overview]
Message-ID: <CAKDxb-rbjS08v7hDFRMQc8VXHDPRjyRKLb_r=3-zXSU6_UHP_g@mail.gmail.com> (raw)

The following are 3 samples of kernel messages that I am getting on a
fairly regular basis, which seem to have started occurring since the
cx23885 vb2 conversion. I am using the
https://github.com/ljalves/linux_media tree from 16 Jan 2015

I have a TBS6985 and a TBS6981 card present in the machine. The
TBS6985 is working fine. The kernel messages are triggered by VDR's
idle scanning which it done using the TBS6981.
