Details:

grub-probe hang on --device /dev/dm-4 --target=disk
This is a device-mapper raid1 partition setup with dmraid.
This is a 64bit system with NVIDIA raid controller.

When interrupting the program is sits in __openat_nocancel() syscall see
grub_gdb.log for more detail.
Continuing execution from within gdb returns the expected results.

This is not limited to --target=disk. But target disk only hangs once, other
targets hang multiple times.
Executing the same command on a USB stick doesn't hang.
grub 2.00 doesn't have this problem.
