Here suspend takes more that 10 seconds:
[ 2165.363878] nouveau [ DRM][0000:01:00.0] suspending fbcon...
[ 2165.363885] nouveau [ DRM][0000:01:00.0] suspending display...

framebuffer(s)...

[ 2174.809084] nouveau [ DRM][0000:01:00.0] suspending client

[ 2177.950222] nouveau 0000:01:00.0: power state changed by ACPI to D3
