I had looked at other relevant threads on askubuntu but I figured it was a kernel issue. I'll certainly work within the context of this bug to try to fix if possible. I'm on 4.9.0-15-generic but I just installed 4.10.0-041000rc6.201701291830 and will reply with results (after removing the line from /etc/default/grub to disable pstate). Relevant info from cpuinfo:

vendor_id : GenuineIntel
cpu family : 6
model : 42
model name : Intel(R) Core(TM) i5-2500 CPU @ 3.30GHz
stepping : 7
microcode : 0x29
cpu MHz : 3311.061
