Bug Description
Binary package hint: grub2
system version : upgraded form Karmic to beta Lucid then regurlarly updated
package version: unknown (system unbootable at this time ...)
The hardware is an Apple Macbook computer with gpt partitions instead of a bios boot partitions (all the recent Apple hardware). The gpt partitions support by grub is more recent than the support for the bios. Bootcamp is installed on the hardware and provides a choice to boot either Linux or Macosx.
steps:
1. aptitude update && aptitude upgrade
2. watch the console output, notice a capital warning about grub2 being unreliable on gpt partition (i know it is vague)
3. reboot the machine
4. watch the bootcamp menu
5. click on the linux
The result expected is the grub menu, but the bootcamp menu stays on, and it is frozen.
I have a 17" Unibody Macbook Pro that had a fresh install of Ubuntu done with Lucid alphas, regularly updated, and I attempted to upgrade grub2 and the system booted fine.
So at least on my machine, I cannot reproduce this bug.
