Comment 9 for bug 872220

I am attaching the dmesg output from a failed boot, unfortunately the mdadm messages don't go to the dmesg log file, I have not been able to find them recorded anywhere but on the screen at this point. The boot dropped into the shell right after the line:

[ 4.201060] md0: unknown partition table

I have found that adding the line:

GRUB_GFXPAYLOAD_LINUX=text

allows me to reliably trigger the error. If that line is not present and I am booting after a clean boot (I would assume I could also set it to keep and have the same effect) I can boot without dropping into the shell.
