Description Alain CADOU 2021-02-27 11:56:06 CET

Description of problem:
The PC boot normally, I complete the user/password fields to start the plasma session and I get a black screen with only a mouse cursor.
In the dmesg output I found this message:
i915 0000:00:02.0: [drm] GPU HANG: ecode 7:1:85dffffd, in Xorg [3328]
The bug is not in the kernel-desktop-5.10.12-1.mga7, so I downgrade to this kernel.

Version-Release number of selected component (if applicable):


How reproducible:
Every cold boot of the PC. 

Steps to Reproduce:
1.Nothing particular, just cold start the PC.
2.
3.

this can be a fallout of the i815 security mitigations.

Can you try 5.10.19-1.mga7 that is in Core Updates Testing

Hi bug reporter and hi assignee and others involved,

Please reopen this bug report if it is still valid for Mageia 8 or 9(cauldron), and change "Version:" in the upper left of this report accordingly.

This report is being closed as OLD because it was filed against Mageia 7, for which  support ended on June 30th 2021.

Thanks,
Marja
