		<h1>cloudchaser issues</h1>
		<p>Lenovo T495 machine, for details about the hardware see: <a href="/articles/T495">/articles/T495</a></p>
		<h2>2021-??-?? - GPU Hangs</h2>
		<ul>
			<li>gstreamer testsuite hangs the whole machine, SSH access is rare, logs are still being written, dmesg often gets errors from iwlwifi</li>
			<li>some random mishaps are there, GPU reset often works, dmesg points to fences</li>
		</ul>
		<h2>2021-08-05 - Upgraded to sys-kernel/gentoo-sources-5.13.7</h2>
		<ul>
			<li>ALSA doesn't have Mic Mute-LED Mode control anymore, stuck to Follow Mute</li>
			<li>Doesn't wakes up from DPMS, nothing unusual in dmesg, no messages by sway</li>
		</ul>
		<p>⇒ Reverted to previous kernel build, sys-kernel/gentoo-sources-5.12.14</p>
		<h2>2023-02-12 - Sway (1.7) + wlroots (0.15.1) segfault</h2>
		<p>On exiting Ponscripter (SDL-based), sway crashed. Here is logs from the debugger:</p>
