you saw that you already got answer above related to your questions for:
sudo dmsetup ls --tree
and
sudo grub-probe -t device (hd3) ?

Oh yes, 3 is an extended partition. Odd. You might try disabling it
with:
sudo dmsetup rm via_hehhchjje3

Title:
grub-probe auto-detection
maybe this also is helpful:
made a diff of
grub-probe -vvd /dev/dm-6
versus
grub-probe -vvd /dev/mapper/via_jehhchjje7
at certain stage /dev/dm-6 just gets opened:
grub-core/kern/disk.c:338: Closing `hd3'.
grub-core/kern/disk.c:245: Opening `hd3,7'...
grub-core/partmap/msdos.c:166: partition 0:
No, it will simply get rid of the device. It will come back after a
reboot. If that is the problem, then removing it temporarily should
work around it.

Sorry about that, I saw the nvraid module and got confused and thought
that was supposed to handle it and there aren't modules for the other
dmraid formats. Now that I think about it, that module is only for
letting grub recognize such an array without the benefit of having the
nvidia raid bios.
