GPU HANG. Kernel 5.15 on TigerLake
Hi,
with kernel 5.15.0 up to 5.15.2 i face GPU hangs on my TigerLake Laptop.
The GPU Hang occurs reproducible when i press the first letter of my login-password in the SDDM-Greeter (3 out of 3). Sometimes the SDDM-Greeter Screen is already corrupted after boot (1 out of 3).
I have downloaded, compiled an booted the last drm-tip and booted with the recommended debug-options before i captured the attached logs.
Hardware: Lenovo ThinkPad X1 Carbon Gen 9, model 20XWCTO1WW ThinkPad BIOS N32ET66W (1.42 ), EC N32HT46W DMI: LENOVO 20XWCTO1WW/20XWCTO1WW, BIOS N32ET66W (1.42 ) 06/15/2021
Distro: Gentoo Linux
Display: Laptop built-in screen
uname -r: 5.15.0-x86_64+
I am happy to provide further information if required.
Many thanks in advance.
Kind regards Stefan
