Ok, here we go: 1. Clone stable kernel from here if you haven't done so yet: $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git 2. checkout 4.20 branch $ git checkout -b 4.20-stable origin/linux-4.20.y 3. apply the attached patch $ patch -p1 -i acpi-dump-cstates.diff 4. copy your 4.20 config $ cp /boot/config-4.20.... .config 5. do $ make oldconfig 6. build $ make -j16 7. install kernel, needs root # make modules_install install # reboot Then, select this new kernel in grub, boot it and upload full dmesg.
