Looks like a BIOS update fixed this, as it hasn't been reproducible so
far, after putting extra ordinary graphics/processor/RAM stress for
days. Should have eaten my own dog food on a BIOS update earlier (I
thought it was latest and greatest as I checked a couple months back for
one). Sorry for the noise.

Title:
1002:9830 [Lenovo IdeaPad S415 Touch] Hard locks watching pepper flash
content via chromium
Status in linux package in Ubuntu:
Invalid
Bug description:
1) lsb_release -rd
Description: Ubuntu 14.04.1 LTS
Release: 14.04
2) Linux monikerpc 3.16.0-25-generic #33-Ubuntu SMP Fri Nov 7 01:53:40
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
3) What is expected to happen is when one watches pepper flash content
via chromium, it does not hard lock the computer.
4) What happens is it does as per attached kern.log. This typically
happens every 2-3 days.
I just updated the BIOS. If it continues, I'll do a mainline test next:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
