See the report for details.
Anyway, I'm adding this to regzbot:
#regzbot introduced: v6.2..v6.3 https://bugzilla.kernel.org/show_bug.cgi?id=217427
#regzbot title: No video output from AMD RX 570 and kernel exploit attempt on ppc64le
Thanks.

It doesn't look like the aforementioned patch made its way into 6.3 yet:

Bugs filed against powerpc do get Cc'ed to linuxppc-dev, so we do see
them. Though that doesn't always mean we have time to fix them :)
I have a talos machine with an AMD GPU, but not this model, and mainline
is booting fine for me. So we'll need the original reporter to do some
more debugging.
Looks like there's a possible culprit identified on the gitlab issue:

In fact, it seems that patch is already part of 6.3:
$ git tag --contains f4f3b7dedbe8
v6.3
v6.3-rc5
v6.3-rc6
v6.3-rc7
v6.3.1
