@pcilela -- there is something odd about how your grub update has gone as you have moved from an root=UUID=xxx form to a root=/dev/sda7 form. So it may be something outside the kernel which is failing here.
Can you try editing the boot line when in grub, to use the root=UUID=xxx form (the exact uuid should be copied from the -12 entry which works) and see if that boots ok. Please report how that work here. Also we should be slightly suspicious of the initrd for -13 given your errors. So could you also run: update-initramfs -u -k 3.0.0-13-generic and report the complete output here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880476 Title: after update to kernel 3.0.0-13 ubuntu 11.10 does not start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/880476/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
