I'm running Fedora Core 6, with kernel 2.6.19-1.2911.fc6. Currently
on SVN r12790.
Since you're running Gentoo, so necessarly compiling, are you able to
share your specific configure settings? I'm currently using this:
./configure --prefix=/usr/local \
--with-bindings=perl \
--enable-proc-opt \
--enable-audio-alsa \
--disable-audio-arts \
--disable-audio-jack \
--disable-directfb \
--enable-lirc \
--enable-v4l \
--enable-ivtv \
--enable-firewire \
--enable-dvb \
--enable-opengl-vsync
I still get "NVP: prebuffering pause" with SD but mostly never notice
it outside of reading the logs. LiveTV was on all day today and still
going. Unfortunately I'm not recording HD yet but I did test a 1080i
mpeg2 playback and that worked fine (I forgot what the CPU usage was
for me but it's always been low). I will be interested to see what
it's like with the HDHomeRun I plan to get, because I could just still
be fighting signal quality issues recording analog with the pvr250.
