Unfortunately I spoke too soon again - this is an intermittent problem and it occurred again this morning (I have now upgraded to Quantal with kernel 3.5.0-17-generic).
I have collected dmesg log files from an occasion when the problem occurred (the screen went blank during the boot process), and also from an occasion when the boot process was successful. I can't see anything particularly worrying in the first file, but I am attaching them here in case someone else can figure out what's going wrong. I've called the log file from the failed case dmesg-bad, and from the successful case, dmesg-good. To help with comparing the files, I am also attaching versions with the initial timestamps on each line removed (these have a suffix -stripped), and also versions of the stripped files where the lines are sorted alphabetically to make it easy to spot which lines are different (with suffix -stripped-sorted). ** Attachment added: "dmesg log file from a failed boot (original file)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1058969/+attachment/3414280/+files/dmesg-bad -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058969 Title: Kernel 3.2.0-31 fails to boot from grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1058969/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
