Linux OpenCL 21.30 broken with RX460

I'm running a RX460 card under Arch Linux using the opencl-amd (AUR) package together with the open source X driver. While the 21.20.1271047 driver gives a nice opencl boost opencl using 21.30.1290604 doesn't seem to work with darktable at all though not reporting any error.

clinfo reports it this way different:

21.20:

Note the memory difference and OpenCL 1.2 vs. 2.0. - I've reported this first to the darktable devs assuming DT misdetects the opencl image support somehow but they ask me to report it back to the driver here:

https://github.com/darktable-org/darktable/issues/10118

 

Any idea what's wrong with 21.30 not speeding up any image manipulation here?

I have the same problem with blender and a RX 570
with 21.20 everything works as expected.
with 21.30 dmesg gets spammed with:
