2021-??-?? - GPU Hangs

• gstreamer testsuite hangs the whole machine, SSH access is rare, logs are still being written, dmesg often gets errors from iwlwifi
• some random mishaps are there, GPU reset often works, dmesg points to fences

2021-08-05 - Upgraded to sys-kernel/gentoo-sources-5.13.7

• ALSA doesn't have Mic Mute-LED Mode control anymore, stuck to Follow Mute
• Doesn't wakes up from DPMS, nothing unusual in dmesg, no messages by sway

⇒ Reverted to previous kernel build, sys-kernel/gentoo-sources-5.12.14
