nope, I double checked and both BE&FE are running as mythtv

I try to limit this and stick with debian packages otherwise I forget what I
did (and how) and things get really ugly...

agreed, but I was hoping that others were using HVR-2250 with myth and could
say if they'd seen and/or fixed similar issues.
I plan on keeping this current version until I see another hang (then I'll
grab tip again). So far I've been up for 3 days through many recordings so
it might be the hangs were fixed by some other fiddling I've been doing.

I had a thread a while ago about updating to a newer 0.21-fixes (
http://www.gossamer-threads.com/lists/mythtv/users/384013#384013) and I
decided it wasn't worth while, but if these hangs continue I'll revisit that
also (after trying newer driver).
My experience: I had similar hard locks with Lenny (but no

I'm using EXT3 for everything with the "delete slowly" flag.

Thanks for info/suggestions Paul. At the moment I'm more or less in a
holding pattern waiting to see if it continues to hang.
The things I've changed recently that probably don't but might have affected
1) added labels to my partitions and changed fstab to use the labels instead
of /dev/sd* - This had the surprising side effect that nmbd will now startup
properly. Previously smbd would start on reboot but nmbd would not start
automatically even though /etc/init.d/samba restart would get both smbd/nmbd
up and running. This one has me stumped but maybe it changed the order that
partitions are mounted in such a way that the shares weren't mounted when
nmbd tried to run before I added the labels.
2) I purged horde3 because it was dumping tons of stuff into my system
logs. I wanted to try IMP but gave up trying to configure it since it was
so complicated and all I wanted was nicer looking webmail than squirrelmail.
3) I unplugged my USB flash card reader because it too was dumping tons of
junk into my system logs (~150 lines per minute in /var/log/messages!). I
don't expect to use it often and when I tried it the first time it didn't
work OOTB so I unplugged it until I have time to figure out why it's so
4) I changed from Normal playback profile to using OpenGL on my GeForce 9300
because I thought it might improve the jaggies I saw on recordings. They
were actually caused by bad SNR so I changed back to Normal last weekend in
case OpenGL was contributing to my hangs.
5) Plugged in my custom made internal SPDIF header to RCA jack cable so I
could use digital audio out from my myth FE instead of the headphone jack.
(I should have bought a mobo with digital audio on the back panel!)
That's all I can remember at the moment, and yes I know most of this stuff
should have no impact on hard hangs but ... :)
