From the bug report:

>>>   "clocksource: Switched to clocksource tsc"

That's a Linux kernel message - so grub is innocent.  It loaded the Linux 
kernel.

I recommend mounting the root by UUID, then it will be found.

It would just be an option.
The user could also specify the device by name.

Having a declarative specification with non-persistent
names in it is dangerous.

Makes sense.
Please file a bug report about it...

I think installing the bootloader on multiple devices is the easy part.

Does it also require grub.conf on multiple devices or is that part already
RAID-aware then?
