commit f0521558a2a8 ("drm/i915: Don't clobber M/N values during fastset
check") may have helped here.
Looks like that one should be in 5.1.15+ or 5.2+. What's the most recent
kernel people have tried here?

The fix is nowhere yet. And judging from the ubuntu bug it may not even
work :(

The log was cut off so couldn't see that PSR was in fact disabled. You
can fix that by passing eg. log_buf_len=2M to the kernel cmdline.
Anyways, after a second glance at the logs
Hmm, yes 4.32 is what the BIOS uses, so this might even help:
[1.391106] [drm:intel_dump_pipe_config [i915]] port clock: 432000, pipe src
size: 3840x2160, pixel rate 533299
Hmm. That probably means this is a victim of commit f11cb1c19ad0

with this panel. Please test.

According to that the sink thinks everything is fine, so no idea why
generates short hpds.
Could be some kind of PSR fail. Please try passing i915.enable_psr=0 to
the kernel cmdline.
