Doesn't appear to be a missed clobber in the md file, as *.expand shows in insn
7 - r22 is in the clobbered registers list. Later passes assume r22 is unused

Apparently, PR target/52484 covered one of the cases in avr.md, but not the
general case of a call to __xload_{1,2,3}. I think adding (clobber (reg:MOVMODE
22))
