There seems to be a problem with the disklabel (see below). However, I
don't think that explains the problem (works with MBR, but not with
GPT).
Further, I couldn't use disklabel(8) to fix the problem. Even creating
a new auto/standard disklabel fails. It kept complaining about an
invalid ioctl.
Any tips on how to debug geom ? I tried "set kern.geom.debugflags=1"
at the bootloader prompt without success.
