Hello
I have a Lenovo Ideapad 310. I was having issues with power management, and was using upstream kernels. I noticed they had frequent freezes, so I decided to use the standard from Ubuntu 16.04 (today, 4.4.0-75). But now it has this freezes too, so something which was bugged on the newer kernel was inserted on 4.4.0-75, as previous version (4.4.0-72) hadn't this issue.
What is happening is: the system freezes. The sound that was being played loops endlessly. Everything freezes, Ctrl+Alt+Fnumber don't work. The system completely stops. Normally, I would just power the computer off keeping the power button pressed. But this time I tried to recover it, as the syslog ended always corrupted. I needed to gets the logs at least once. So I started to disconnect hardware parts: battery charger, external USB HDD (it was not being accessed), USB mouse, USB keyboard. When I disconnected the sound jack, I noticed the mouse moved, so it was recoverable.
I waited for 100 seconds until the system recovered. When it recovered, looked like nothing had happened, and now I'm writing this report from the computer, without restarting.
Steps to reproduce:
1) open Audacious or VLC;
2) play a music/video on Audacious or VLC;
3) open another program with sound (Steam, a browser (I use Opera), etc);
4) use the computer until a freeze happens.
Observations:
-Audacious + Steam + Starbound is nearly 100% chance of triggering it (SDL?).
-VLC + Opera + Firefox (on start page) was enough for trigger it once, even with the only program with media opened being VLC.
The freeze I was able to recover had: Opera Developer (YouTube video playing) + Audacious (playing) + Steam with audio streams opened on pavucontrol. Additionally, Thunderbird and Evince were opened, and intel-gpu-overlay was opened inside a Xnest window.
The syslog says to report to alsa, so I'm writing the report here. However, it should be noted that there is a i915 error too, maybe it was a consequence, maybe it was the cause.

Thank you.
Edit: one thing I noticed with indicator-multiload, the internal HDD activity completely stopped while this problem was happening and soon after it started to function. It was like the computer was recovering with the internal HDD turned off. The HDD usage ramped up and the system returned to normal. May this be related with the power management issues?
