I have not been able to test the upstream kernel - it seems to be unable to set my graphics card to produce any output.
However, I have been able to create a fresh install of 12.04 on a different hard disk - the other hardware exactly the same, just a different hard disk. I started with the original 12.04 CD and then took all the available updates including 3.2.0-56 so that the setup should have been as near as possible the same as the one that caused trouble. The result is - it seems to run just fine. Hence at the moment my assumption is that the problem was due to some unidentified mishap during the update to 3.2.0-56. I am intending to do an install of 13.10 to a different hard disk. When I have that established as a working environment I will try a surface scan of the disk with the problem setup and perhaps try to uninstall and reinstall 3.2.0-56 to see what happens. I do have a copy of the relevant kernel log showing call stack dumps and 'BUG' messages that I could add if you think it would be of any help. Otherwise I will update this report if I can find anything that might be of interest when I am in a position to investigate further. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1249758 Title: 12.04 freezing after update to 3.2.0-55/56 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1249758/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
