Sadly (?) I'm going to have to punt on this whole MythTV/Mythbuntu
upgrade experience.   Yes, I had to tweak mythburn.py to get it working,
but I sort of expected that.  But the real dealbreaker is the occasional
"NVRM: os_schedule: Attempted to yield the CPU while in atomic or
interrupt context" and associated Xorg hang that I'd experience.  IOW, I
went from a system that worked fine to one that's unstable.

Googling the above phrase gives me a number of discussions where people
are exchanging boot kernel flags or other tweaks that maybe sorta help
the problem.   And people sharing stories of how they've been able to
achieve uptimes of a day or so.

I tried a couple of different nvidia driver versions as well as boot
flags, but none seemed to come together to produce a stable system.
Getting a solid nvidia driver version was a bit of a pain when I first
set up the HD-capable Mythtv system 2 years ago, but the apparent fact
that nvidia driver stability/reliability hasn't seemingly improved since
then is completely ridiculous, IMO.

While MythTV itself seems to be fine after the upgrade, if the nvidia
drivers aren't stable, then I consider it a failure.  Would upgrading
the system to Mythbuntu 12.10 (and subsequently kernel 3.5) address the
problem?    Maybe?   Is there some combination of kernel / drivers /
options that gives stability?  Possibly?

That's too much uncertainty * time-spent, with the possible outcome of
having something that works as well as what I had before.  I've passed
the threshold of restoring from backup being the best way "forward."

Sorry for the rant, but I just had to vent a bit.
If somebody can definitively say that it's a known bug that is proven to
be fixed in kernel/driver version foo, then I may revisit the whole
upgrade experiment again.  But for now, I'm back to the theme that I
should have stuck with from the start:
If it ain't broke, don't fix it!
