Bug Description

After upgrade the system does not boot.

This bug is converted from question: https://answers.launchpad.net/ubuntu/+source/grub/+question/89461

Original reported (from the question) is Zaki.
There where comments with 3 confirmations.

This bug is present also for me (LimCore) after just aptitude safe-upgrade after installing clean 9.10 amd64.
The original reporter Zaki had the problem after upgraded from Jaunty to Karmic.

I am having this error after the grub
  udevadm trigger is not permitted while udev is unconfigured.
  udevadm settle is not permitted while udev is unconfigured.
  svgalib: cannot open /dev/mem
The PC does not boot.
It drops into (initramfs) shell.

This is not an error of the bootloader, but of a broken initramfs generated while udev was in an unconfigured state. This is not supposed to be possible, but I've seen this error before as well; reassigning to apt, and marking as a duplicate of bug #453678.

To work around this error, please select the previous kernel from the boot menu, open a terminal, and run 'update-initramfs -u' to regenerate the initramfs for the 9.10 kernel.
