Comment # 3 on bug 1180380 from Takashi Iwai

Could you give the dmesg output with drm.debug=0x0e option (you can set
dynamically via /sys/module/drm/parameters/debug) around suspend/resume?

Also, is this a regression during Leap 15.2 release?

And, just to be sure, could you check either SLE15-SP3 kernel-default?
