Comment 17 for bug 778520

Apologies if I'm misunderstanding something, but I'm not sure this bug is fixed in Oneiric.

I've tested this in virtualbox with both the server 64-bit beta2 and the daily build server 64-bit for Sept. 27th. If I've hit this same problem, it's 100% reproducible.

Two virtual disks, with /dev/sda1 /dev/sdb1 as raid 1 /dev/md0 for /.
/dev/sda2 /dev/sdb2 as raid 1 /dev/md1 for swap.

If I "disconnect" one of the drives, on booting the grub countdown appears, and then the screen goes black. The only response I can get from the machine is if I blindly press 'enter', then type 'reboot', then press 'enter' again, which causes the virtual computer to reboot. It doesn't matter which of the 2 disks I 'disconnect.'

So far, this has happened 100% of boot attempts. If I reattach the disk, it boots fine.

Apologies if I've misunderstood something. I can do some virtualbox testing if that would help.
