Similar random reboots with a amd64 kernel in the cases with the same CPU were reported (quite a long ago,for Ubuntu 9.04) there: http://ubuntuforums.org/showthread.php?t=1137153
They also say that some other distros also had this problem (e.g.,Gentoo), but there were successful boots of some Knoppix and Mint distros. That discussion is of course about a completely amd64 system, not like in my experiment (amd64 kernel + i386 userland). So, it well might be a problem notrelated to my experimental mixof amd64 and i386. I wonder whether there has been found a workaround ever since. (In my case, it's that simple: if the bootup succeeds, there are no more problems/reboots for hours and even days.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1495116 Title: booting with amd64 kernel and completely i386 userland is unstable during the system upstart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1495116/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
