AMD Ryzen 3400g Freezes

Hey everyone,
random freezes with my AMD Ryzen drive me crazy lately. I wonder if anyone over here is running a similar setup and may be able to help. I am on a Lenovo Thinkcentre M75s-1 with two DisplayPort monitors. Things I have tried:

fresh system install last week after 4.2 was released.
tried the different kernel parameters as discussed here: https://gitlab.freedesktop.org/drm/amd/-/issues/934.
disabled snd_hda_intel for the hdmi device
disabled usbcore.autosuspend

The latter two seem generally promising, since I have had only one freeze since (which is a crazy thing to say). The relevant journalctl gave:

[drm:amdgpu_dm_commit_planes [amdgpu]] *ERROR* Waiting for fences timed out! ... [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=5057339, emitted seq=5057341 [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process Xorg pid 938 thread Xorg:cs0 pid 951

That is after firefox spammed the logs with:

g_hash_table_contains: assertion 'hash_table != NULL' failed

and

[Child 2485, MediaDecoderStateMachine #5] WARNING: Decoder=7fdbf0490400 Decode error: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - RefPtr<MediaSourceTrackDemuxer::SamplesPromise> mozilla::MediaSourceTrackDemuxer::DoGetSamples(int32_t): manager is detached.: file /home/build/YPKG/root/firefox/build/firefox-85.0/dom/media/MediaDecoderStateMachine.cpp:3465

I'll continue to investigate and can provide further logs if necessary.
