Hey David,

I have not been able to use a new /boot/loader.efi (following -CURRENT)
since 
mid to late 2021, and your symptoms look the same; fortunately, I found
bug 
report 264282[0] last night, which I think is related. Yamagi has
already done 
the investigation, and found a possible cause. For the time being, in
the case 
of a GELI backed UFS mount, after GELI decrypts the mount, one has to
manually 
set currdev back to the correct disk.
