[mythtv-users] Upgrade to 0.18 / 7174 Problem

All at once, I decided to upgrade to 0.18 and do a dist-upgrade on my FC3 
system.  That upgraded many things (over 150 updates), including my nvidia 
drivers (from 6629 to 7174).  Immediately after doing this, I had quite a 
few problems.  Most of the problems were due to the new packaging layout at 
atrpms.  One wasn't.  Whenever I tried to go to the previously-recorded 
programs screen, the frontend would freeze, X would take up 99.7+% CPU time, 
and all would stay like that until killed.  I got errors like:

Apr 22 22:14:37 mythbox kernel: NVRM: loading NVIDIA Linux x86 NVIDIA Kernel

Apr 22 22:14:37 mythbox kernel: NVRM: not using NVAGP, an AGPGART backend is 
loaded!
Apr 22 22:14:37 mythbox kernel: NVRM: not using NVAGP, an AGPGART backend is 
loaded!

which suggested an agp driver problem (though I didn't change kernels and 
wasn't getting these errors with the same xorg.conf) and

Apr 23 00:42:22 mythbox kernel: Disabling IRQ #9

which suggested a problem with a device on IRQ 9 (such as my M179 card, 
which worked fine for cat > test.mpg).

Mythfrontend and backend where curiously silent about a problem that only 
seemed to crop up while accessing the recorded programs screen.  Realizing 
that I could playback things using xine and mplayer, and that I could watch 
livetv, it seemed like there could be a problem with accessing the database 
to display information on the saved programs.  But dropping the database and 
starting from scratch didn't help.  So, all my google searches were for 
naught.  Nothing helped in the least.  Just for kicks, I started re-reading 
Jarod's guide, to see if there was something that I might have to reset 
after doing a dist-upgrade.  While doing so, I noticed an interesting thing:

>>
Not sure exactly what has changed in the nvidia driver, but most folks no 
longer seem to be able to use the RenderAccel line without having problems. 
However, I'm not sure what added benefit it provides anymore, since contrary 
to my earlier belief, it isn't necessary for me to use XvMC... With 6629, I 
didn't have any problems with it on any of my motherboards with VIA chipset 
or nVidia's own nForce2 chipset, none of which play nice with RenderAccel 
enabled anymore, but it doesn't seem to make any difference, I can still 
play back even HDTV video just fine without it.

And what do you know - commenting out that line in my xorg.conf solved the 
problem right away.  For what ever reason, having RenderAccel on didn't 
affect my ability to play back video at all, unless I was trying to access 
that one screen.

So, the short version:  7174 and RenderAccel don't seem to play nice on the 
Chaintech 7NIF2's built-in graphics card.

Now that it's working, I'm off to have fun with 0.18!
