GPU HANG: ecode 9:1:85dffffb in Xorg
GPU crashes multiple times per day when an external display is connected (HDMI or DP). I haven't observed similar hangs when the external display is not connected.
OS:
- Fedora 33
- kernel 5.11.0-0.rc6.141.vanilla.1.fc33.x86_64
Reproducible also on Fedora 32, and F33 with the default kernel (v5.10).
Hardware:
Manufacturer: LENOVO
Product Name: 20EQS64N0G
Version: ThinkPad P50
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
