PATA_CMD64X works fine on my 164LX for many years, last tested with 5.12-rc3.

Indeed it started to fail somewhere between v5.6 and v5.7.
v5.7 fails early with few messages on the console with reboot, v5.8 and
later hang right at bootloader.

I can reproduce the same problem on a powerbook G4, and no,
CONFIG_KASAN=y kernel with that patch reverted also does not boot with
