Subject: Re: Possible regression on suspend (mem/s2idle) between 5.15 and 5.16

Hi,

 sorry for top posting, but this is likely important enough. The
problem seems to be gone with 5.17-rc4. So I guess there is some
potential for putting a fix into 5.16.x. If that rings a bell, I am
happy to test that. Unfortunately I do not have the time for
bisection.

Adding the Nouveau list

Cheers
Martin
