That looks like the same bug as 542435 which was caused by dmestup
2.02.51-1 but fixed in the next upload 
Please make sure you're using the -2 version and then execute `echo
change > /sys/block/dm-0/uevent'
Then the /dev/mapper/* files shouldn't be anymore symlinks and
grub-probe should work again.
