| Summary | Hang on resume [AMD/ATI] RV515/M54 [Mobility Radeon X1400] |

I've got Dell Inspiron 6400 with Ubuntu 16.04, oibaf drivers and kernel 4.7.3. The box doesn't seem to be able to come out of STR - it just hangs with black screen. I've tried 'echo devices > /sys/power/pm_test; echo mem > /sys/power/state' and on resume I often get to see my desktop but then box completely freezes - no keyboard, no mouse, no net. I've tried suspending/resumeing in console mode and could not reproduce this problem. On previous Ubuntu kernels (stock) it hangs often, but sometimes it is able to resume, in 4.7.3 it seems to be handging close to 100% percent of the time. Unfortunately I'm not really able to get any debug logs since box gets totally frozen. Is there any way I can provide any more information or debug this? Thanks!
