GRUB error: unknown filesystem on ia64

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Hello!

It seems that one of the security patches has caused a regression on ia64 as
GRUB is no longer able to load any basic commands:

Loading.: grub                                                              
Starting: grub                                                              
Welcome to GRUB!                                                                                                                                                                                                                                         
error: unknown filesystem.

grub rescue> insmod ext2
error: unknown filesystem.
grub rescue> help
Unknown command `help'.
grub rescue> ?

grub rescue> linux

I have not bisected the issue yet, but maybe anyone has got any idea?

Adrian
