Description Mike Burgener 2023-06-16 07:39:45 CEST 
Hi everybody,
looks like Kernel 6.3 is in big trouble when using the nouveau driver, see https://www.phoronix.com/news/Avoid-Nouveau-Linux-6.3

Taken from https://blog.mageia.org/en/2023/05/24/the-release-of-beta2-brings-mageia-9-stable-closer-to-reality/ mageia uses 6.3.3 on Mga9, thus this is release-critical, as it may break everything even already in early install stage when using the nouveau driver. please have a look at it and decide if it is critical after review.

BTW i could not find the mga9 Kernel 6.3 package anywhere on https://madb.mageia.org/

Kind regards

A patch seems available now in the gitlab freedesktop issue
Comment 3 Morgan Leijström 2023-06-16 09:43:38 CEST 
Cauldron/mga9 is currently at 6.3.8

I guess our kernel wizard is into it already

Perfect, is it tmb? If so, he is not a wizard, he is a reincarnation of Merlin in terms of Kernels :D

Yes, 
I'm aware of the issue and have been monitoring it while upstream folks was figuring out how to root-cause and fix it...

I'm currently travelling so it will be a few days before a new kernel will land ...

I have not had that issue.  Maybe hit-n-miss or only certain Nvidia chips?  Just guessing..

Created an attachment with specs.

From the report, it only causes major problems some cards. The problem
with memory corruption, is that it may or may not cause noticeable issues
depending on what gets corrupted. If it triggers file-system corruption
the damage is permanent, but depending on which files get corrupted, the
corruption may or may not be noticeable.
Comment 10 Thomas Backlund 2023-06-19 18:46:42 CEST 
Upstream fix merged in kernel-6.3.8-2.mga9 (currently building) and will be on public mirrors in some hours...

Resolution: (none) => FIXED
