With latest Lucid packages (and, at instance, nvidia driver 256.35) I
experienced no more freezes. From time to time I have some ACPI error message,
but occasionally.
For what is concerning the usb tv tuner Pinnacle Hybrid pro stick, I realised
the driver v4l-experimental and/or the firmware xc3028 don't completely support
my tuner. In order to have full support, I need to load the driver with the
option card=11, then reload it with the option card=53.
In short:
modprobe em288xx card=11
rmmod em28-dvb
rmmod em28xx
mordprobe em28xx card=53
In order to achieve this goal, I wrote the UDEV rule:
ACTION=="add", SYSFS{idVendor}=="eb1a", SYSFS{idProduct}=="2881",
RUN+="/usr/bin/test_avvio_em28xx"
It launches the script:
modprobe em28xx
sleep 2
a=`dmesg | grep em2880-dvb`; sleep 2
sleep 2
if [ "$a" = "" ]
then sh /usr/bin/em28xx_card11
fi
and then:
a=`ls /dev/dvb/adapter?/`; sleep 2
if [ "$a" = "" ]
then rmmod em28xx-dvb; rmmod em28xx; modprobe em28xx card=53; sleep 2; rmmod
em28xx-dvb; sleep 2; rmmod em28xx; modprobe em28xx card=11
fi
the problems with this solution are:
1.) the driver loading is very slow, as if the system is experiencing a "loop"
2.) sometimes I have problems with the hibernation (or better, the waking up
after hibernation)
I think the real problem is connected with the UDEV rule, but I didn't
find a better solution yet.
