GPT - Raid 1.2 & Grub 2 [SOLVED]

[thild]

Hello,

I have successfully installed gentoo with the following configuration a few monthes ago:
- Grub(2) bootloader (9999)
- /boot on /dev/md1 (RAID1 metadata 1.2 /dev/sda3+/dev/sdb3)
- all other volumes (including root) are managed under LVM using /dev/md2 as a PV (RAID1 metadata 1.2 /dev/sda2+/dev/sdb3)
- /dev/sda1 & /dev/sdb1 are reserved as BIOS boot partition for grub(2)

Last week, I have updated grub.
I am updating my packages quite frequently (2-5 days), so the previous installed grub (always 9999) was probably the most recent until last week.
Since this update, the system stopped booting.
Grub starts normally (I get the Grub menu displayed). The grub configuration seems valid:
- close to the previous one
- GPT and MDRAID1 grub modules are loaded (I cannot remember the exact module names)
- dodmraid, dolvm and other relevant parameters are passed to the kernel as usual (no big difference with the previous working configuration)

But as soon as Grub boots the default boot entry (latest working kernel with the previous Grub configuration), the platform reboots (I can barely see the kernel name and perhaps the initrd name displayed on screen before it restarts).
I cannot revert back to the previous Grub configuration (I'm using 9999 so this is a risk that I have already accepted).

Now I'm trying to find a solution:
- I have tried grub-2.00_beta0 with the same result
- I have tried using extlinux but it seems still not working with raid metadata 1.2 (the latest news I have found on this particular subject are that it is known to be working with metadata 1.0)

Has anyone experienced successfully or not this type of configuration lately ?

I have re-emerged grub-9999 yesterday, reinstalled boot blocks on sda and sdb and rebuilt the config files.
The platform boots again.
I guess something was fixed on the grub trunk, don't know what yet.
I would have to dig in the changesets commited this week.

As a good practice, I have done the following:
quickpkg --include-config=y grub

So next time I fall in the same issue, I can revert back to the previous working grub binaries.

It was a bug in grub2 around linux command. Workaround was to change linux with linux16 in grub.cfg
