I read that thread and unfortunetly there isn't much similarity to
hardware/setup. The only thing in common is that nothing is being
recorded, and its related to DVB only. Different version of Myth,
different kernels, different hardware. My Kworld card uses the saa7133
module which is included in the kernel ( 2.6.20-1.2944 ). I looked on
linuxtv.org and I didn't see an updated version of that driver.
The thing that is frustrating is that the box has been working fine
since I installed the card in the beginning of September. The only
thing that has changed since then was the addition of another hard drive.
The only thing I can think of as that disk fills up ( I used about 45%
of the space in that Volume group ) and I get farther out on the plater
IO slows down. But that doesn't make any sense.
And I really don't want to try and debug the problem because I don't
want to miss any recordings. I guess I can wait until Tuesday and not
shadow any of my recording and see if it happens again. So far it only
happens when I shadow a recording, we'll see if that holds true.
