Tentatively, the system crash does not occur after installing Ubuntu 12.04 from a CD on the original system that exhibited the crashing.
After installing from a CD, it shows: # uname -a Linux michael-MS-7596 3.2.0-39-generic-pae #62-Ubuntu SMP Wed Feb 27 22:25:11 UTC 2013 i686 athlon i386 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1162555 Title: repeatable system crash related to bttv kernel module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1162555/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
