SubjectRe: [REGRESSION] Graphical issues on Lenovo Yoga 7 14ARB7 laptop since v6.0-rc1 (bisected)
From
Hi August,

Can you provide a dmesg log with drm.debug=0x16 enabled in kernel cmdline?

I wasn't aware that there are currently psr su edp panel + rembrandt apu
systems out in the wild. In any case, psrsu + rmb should be working, and
there might something specific to your configuration that's hitting a
corner case. The dmesg will shed some light.

Thanks
Leo
