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 I see the sink does sometimes
indicate that the receiver port was not synchronized. Not sure why the
failure manifests at that level with the link otherwise being reported
as stable. Looks like we could try to reduce the link rate a bit and
still have enough bandwidth for the 4k@60 mode. I'll attach something to
that effect.
