I am also getting this, with kernel 5.10.45 from NixOS 21.05, with a Dell Inspiron 7573.

I got this for the first time (at least since few a few years, might have helped ef6eaf27274c0351f7059163918f3795da13199c) when I enabled resume-from-USB in the UEFI settings and tested it out. My guess is something to do with the resuming control flow caused ret_size to underflow and this don't happen normally.
