[drm] *ERROR* `lttpr_caps` `phy_repeater_cnt` is `0x0`, forcing it to `0x80` in journal. Why?

When I reboot, I often see something akin to:

amdgpu 0000:59:00.0: [drm] *ERROR* lttpr_caps phy_repeater_cnt is 0x0, forcing it to 0x80

Has anyone else seen it? Do you know why it’s repeatedly posted to the TTY in boot-dmesg mode?

I ask because checking the boot log for repetitions has already allowed me to report gitlab.freedesktop.org/drm/amd/-/issues/3248, so I’d like to ascertain whether it’s expected, in order to reduce the superfluous logs further.

This persists across an OS reinstallation.
