Just FYI:

the recent Nvidia driver works with this kernel.

But I guess that I rather wait with the integration until a 'better' 6.1 kernel is prepared?

[donald]

Great! It looks like we already have patches to fix the mdcheck problem 1 so you'll get a new 6.1 kernel to try shortly :-)

#2985 if you find time.
