GPU hangs with coreboot 4.11 in Gentoo
I have used intensively my laptop for the first time for the 36c3 and I got a fairly decent amount of screen flickering, along with GPU faults in my kernel log and out-of-the-blue shutdown.
I updated to the latest coreboot today just to check, tried to debug all I could from the i915 driver and it seems to be unrelated. So either latest coreboot has an issue or my replacement laptop has an issue.
he gets this error message in dmesg:
[ 1.177709] [drm:gen8_de_irq_handler] ERROR Fault errors on pipe A: 0x00000080
Here are the Dmesg logs: log-gentoo.txt
He uses Gentoo, and his issues are post boot.
He also has an issue with the screen tables, but that is not a main issue.
User reverted to version 4.9
