I recently did a fresh install to R6 from a system that had been running R5.5 over a year with no major problems. Shortly after the upgrade I would get kicked back to the menu when trying to tune to analog channels. I have a PVR-500 for 2 analog tuners and an HDHomerun for digital. I saw some ivtv errors in mythbackend so I added noapic to the menu.lst for grub, shut down and unplugged the power cord from the computer for a couple minutes and powered it back on. I am still having the same issue. What I have found:

/dev/video0 gives errors when selected.
/dev/video1 seems to work fine.

/var/log/mythtv/mythbackend.log info:
Code:

Any ideas on what I can do to troubleshoot this problem? I don't remember it occurring even once with R5.5 and the only hardware change was a new hard drive when I did a clean install of R6.

I have been using a PVR-500 for years and I had problems with the initial R6 release, so I waited for 6.02. That being said, I tried 6.02 and it works well with the PVR-500. I had to physically reseat the card (I must have bumped it).

A friend gave me a 30 GB IDE HDD, so I use that as my test drive for when I want to try something significantly new (like moving from KM to LinHES). I like to know that my components are "known to be good" before introducing new software.

If it helps, I ran a similar test to the one to yours. Results are provided for you to compare against your results. This is the result from a working LinHES 6.02 system with a PVR-500:

Code:
[root@mythtv]# dmesg | grep -i ivtv

Actually, I should have followed up on this long ago. I found that if I reload the modules once the system is up, it works fine. I use mythwelcome so I just changed the mythfrontend command to a script I called:

mythfrontend-ivtv.sh
Code:
#!/bin/sh
sudo /sbin/modprobe -r ivtv cx25840
sudo /sbin/modprobe cx2580 debug=1
sudo /sbin/modprobe ivtv debug=1023
/usr/bin/mythfrontend -d -l /var/log/mythtv/mythfrontend.log
The problem has not resurfaced since.[/code]
