Unnecessary. I closed both PRs that related to GPT. One is pilot error
(using the -k option with gpt migrate is the root cause and as the gpt
manual mentioned, is only there for debugging purposes), the other has
been fixed in -current and is not in anyway going to cause problems
for 5.3.

The bottomline is: you have both MBR and GPT partitions on the same 
disk.
This is not going to work and the cause of your problems. When no file
systems arre mounted on the disk, GEOM presents all partitions, 
including
the device files. The moment you mount, one of the slicers (and its
partitions with device files) disappears. This is what you've been 
seeing
and it has nothing to do with ACPI. It's just timing issue.
