Post subject:  Help, system stopped working all of a sudden

Well after working flawlessly for a month, my system stopped working this morning. I turned on live tv and after about 10 seconds it froze. Requiring a reboot. After several restarts and retrys I discovered the following on my console screen:
ivtv: ENC IRQ OVERFLOW: #xxxx stealing a buffer, 1024 currently allocated


This was scrolling down with xxxx being an ever increasing number. Any ideas? I tried rerunning mythtv-setup but it did not solve the problem. Nothing has changed in the past few days, and I was watching live TV all day yesterday and the day before

Did you do a cold boot? Sometimes hardware gets foobared to a point where a complete shutdown will take care of problems like this.

I think this is a bug that I read about recently. There is a workaround that has to do with settings, but I don't remember the details. I'll try to add the link back on this post if I find it. Someone else is also having a similar problem: http://mysettopbox.tv/phpBB2/viewtopic. ... 2642#22642

Look on the bright side, it's a useful skill to have. ;-) I once won a bet by doing an entire procedure typing with my nose. ;-)

OBTW - useful information - remove that file and restart everything. When you're not watching live TV the /cache partition should look like this:
Code:
root@black:/myth/mythburn# find /cache -ls
     2    4 drwxr-xr-x   4 root     root         4096 May 31  2004 /cache
    11   16 drwx------   2 root     root        16384 May 31  2004 /cache/lost+found
    65    4 drwxrwxr-x   2 mythtv   mythtv       4096 Apr  2 14:23 /cache/cache

By check, I think cesman also means fsck it as well.
