Just as a follow-up, the long time seems to have been caused by ftrace.

With the patch below on top of drm-tip from this morning, it only takes 7 ms.

Interesting. I wasn't aware that ftrace could have such negative side effects.

Anyway if somebody has a radeon in a box with halve a TB system memory he can probably live with a few ms resume time :)
