Package: grub2 Version: 1.98+20100804-14+squeeze1 Severity: wishlist Tags: squeeze
Hello. I've two bugreports reported against qemu-kvm package about squeeze virtual machines being unbootable. These are #653068 and #616487. It all boils down to the following message during boot (from #653068): Loading Linux 2.6.32-5-amd64 ... unaligned pointer 0x93940002 Aborted. Press any key to exit. After some investigation it turns out this is a problem in grub itself, its memory management. In particular, I found this: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/717445 In this bugreport, they found out that later grub versions does not show this issue. This is confirmed by my bureports -- installing grub from wheezy makes it work. In the LP#717445 there's a backport of a large commit to grub made by Serge Hallyn. He backported a commit which made lots of changes to video subsystem handling, see https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/717445/comments/11 I tried the 3 patches against grub in squeeze, had to tweak some stuff in there, and can confirm it fixes the mentioned problem, which confirms what ubuntu guys discovered. Now, the question. It is definitely worth to fix this bug for squeeze, so it will be actually installable in qemu/kvm. It is obviously not possible to fix it for past squeeze releases, so original squeeze will remain uninstallable which is sad. It is not really possible to fix it in qemu/kvm because tje behavor - as far as I can see - depends on quite some randomness. And finally, the backport of that large patch is, well, large and may be too risky for squeeze if it is about to fix just qemu/kvm problem. Any opinions/comments? For now I'll merge the two mentioned bugreports into this one, and mark it with Severity: wishlist.
