I just experienced this bug on 4.10.0-21-generic #23-Ubuntu.
My Firefox stopped responding, and when trying to kill Firefox the Firefox process became un-killable used 25% CPU time and N/A memory.
CPU: 3 PID: 2558 Comm: firefox Tainted: G OE 4.10.0-21-generic #23-Ubuntu
This is the first time I have seen the issue. I have been running 17.04 for two or three weeks.
