[mythtv-users] massive ivtv lockups

[Michael Carter]

I need help debugging my lockup problem. My system has become almost unusable
after upgrading to kernel-2.6.10-1.9_FC2 (which I need to support my newer
pvr-350)

mythtv-0.16, pvr-350 TV-Out, Asus P4V533MX, writing to NFS share. 

# rpm -qa |grep ivtv
perl-Video-ivtv-0.13-6.rhfc2.at
kernel-module-ivtv-2.6.8-1.521-0.1.10-48.3_pre2_ck100zz.rhfc2.at
ivtv-firmware-dec-2.02.023-4.at
ivtv-firmware-enc-2.04.024-4.at
ivtvdev-0.8-1.rhfc2.at
ivtv-firmware-1.8a-4.at
ivtv-kmdl-2.6.10-1.9_FC2-0.2.0-62_rc3d.rhfc2.at
ivtv-0.2.0-62_rc3d.rhfc2.at


Almost every FF or RW (and sometimes just initiating playback) results in a
system lockup. Most of the time, the following messages are reported on my
serial console:
