Package: bttv
Severity: grave
Justification: causes non-serious data loss

The TV image from the tuner is heavily dropping frames. Change appeared 
sometime during a previous dist-upgrade. Cannot pinpoint exact moment.

Diagnostics:

* dmesg:
bttv0: timeout: drop=16 irq=68/68, risc=30d0c97c

tvtime: average blit time: 9.50 ms, average render time: 3.11 ms
tvtime: Last frame times top-to-bot: 522.82 ms, bot-to-top: 19.50 ms

* I have tried with two different TV tuners (ATI TV Wonder VE and a 
Jetway/Kworld). Same issue.

* Frame drop stops during heavy disk IO or CPU usage.

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.0 / Wheezy with a severity
less than important.

We don't have the ressources to reproduce the complete backlog of all older 
kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with 
Debian Wheezy
or a more recent kernel from testing or unstable, please reopen the bug by 
sending
a mail to cont...@bugs.debian.org with the following three commands included in 
the
mail:

reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks

Cheers,
        Moritz
