Some news: I wasn't able to finally find out which driver is responsible for this problem. Especially upstart makes it extremely compilicated. What I found out: the problem most often occours when cold-booting my pc. I assume, once some firmware parts are loaded, also normal boots work. In other words: I have to turn off my pc for some time so that even the last part of ram forgets its firmware. Otherwise I'm not able to repeat such tests. And without a kernel log which is printed immediately to screen, I'm not able to see which module is responsible for it.
I made this hack now which made my problem disappearing for at least 3 days: cmdline: init=/sbin/inithack --- cat /sbin/inithack #!/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin for m in tda8290 tda9887 cx8800 cx88_alsa cx88xx tuner tuner_simple tuner_types tveeprom v4l2_common v4l2_compat_ioctl32; do sleep 1 echo dmesg | tail -4 echo -n " Loading $m : " modprobe $m done echo echo echo "Calling init $* ..." echo exec /sbin/init "$@" --- It is a quite ugly hack actually and it costs me about 11s of boot time. But it is still much better than a frozen pc which needs a cold reset. My conclusion: Once again I see that the problem does not occour if the modules are loaded just one by one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016731 Title: cx88xx freezes kernel when using SMP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1016731/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
