  13. 		<h2>2021-??-?? - GPU Hangs</h2>
  14. 		<ul>
  15. 			<li>gstreamer testsuite hangs the whole machine, SSH access is rare, logs are still being written, dmesg often gets errors from iwlwifi</li>
  16. 			<li>some random mishaps are there, GPU reset often works, dmesg points to fences</li>
  17. 		</ul>
  19. 		<h2>2021-08-05 - Upgraded to sys-kernel/gentoo-sources-5.13.7</h2>
  20. 		<ul>
  21. 			<li>ALSA doesn't have Mic Mute-LED Mode control anymore, stuck to Follow Mute</li>
  22. 			<li>Doesn't wakes up from DPMS, nothing unusual in dmesg, no messages by sway</li>
  23. 		</ul>
  24. 		<p>⇒ Reverted to previous kernel build, sys-kernel/gentoo-sources-5.12.14</p>
