Hello!
I have found some strange behavior of geom_part(gpt|mbr|bsd|ebr) modules.

Kernel can't boot if your kernel config contains these options and you add geom_part(gpt|mbr|bsd|ebr)_load="YES" to loader.conf

I have made some tests with default 9.0R and 8.3B1:
9.0-RELEASE i386 default gpt ufs
geom_part_gtp_load - boots ok
geom_part_mbr_load - boot stops (on usb detect)
geom_part_bsd_load - can't mount fs
geom_part_ebr_load - can't mount fs


8.3-BETA1 amd64 default mbr ufs
geom_part_gtp_load - can't mount fs
geom_part_mbr_load - boot stops (on usb detect)
geom_part_bsd_load - can't mount fs
geom_part_ebr_load - can't mount fs
>How-To-Repeat:
Just add to loader.conf these options
geom_part_gpt_load="YES"
geom_part_bsd_load="YES"
geom_part_ebr_load="YES"
geom_part_mbr_load="YES"
