Thanks, seems it's the Mesa 19.3 branch that contains the grate driver. I will try and build that one. The last build I did was 13 May 2019 when Autotools...

Thanks for the info. I can confirm the 19.3 branch of Mesa builds fine, along with the other components including libvdpau-tegra. Maybe put a note on the wiki page to...

Thanks again. I built the grate-driver kernel (5.8.0-rc4...) and that doesn't have the problem with clk.c oops or the nvec failing to reset/touchpad freezing. I also rebuilt the libdrm, xf86-opentegra,...

Here are cold and warm boot dmesg of master branch as of 4 Aug. One patch has been applied to fix the 'incomplete power off" issue with AC100. This is...

The bad commit causing the power-off issue was identified with a git bisect on the linux-stable tree, which I assume means it is definitely the culprit. I also built 5.7.9...

Thanks for your advice! The EC does shut down reliably on power-off (battery doesn't drain, or very slowly) once the commit mentioned is reverted. Because, I assume, the shutdown message...
