No, booting older kernels doesn't work either. What usually does work, however, is to boot any kernel in recovery mode and then hit "resume" in the recovery menu. Booting this way, graphics will look a bit jaggy, and two CIFS mounts will be missing. I vaguely suspect that the problem may be related to the CIFS mounts, but haven't been able to confirm it, so far.
Unfortunately, all of this happens before the netconsole will start transmitting messages to the machine which does the logging, so I'll be glad for any hints what I might do to defer the crash until later in the boot process. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1403868 Title: Lockup during boot with latest 14.10 and 14.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1403868/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
