 I've tracked the corruption down to this location in the code in line 817
 in function puffsop_msg() in "src/sys/fs/puffs/puffs_msgif.c":
                        memcpy(park->park_preq, preq, pth->pth_framelen);
 This line is probably supposed to copy the request back into the caller's
 structure after handling it. But for some reason the passed in copy
 is incomplete or corrupt.
        Kind regards
