It looks like my issue is a combination of i915 and intel_pstates.
I'm following the thread at this bug:

ACK!
I hit the hard-stop(total freeze) about 10-mins after submitting comment
#7.
I rebooted into single-user-mode(runlevel 1) and uninstalled the
upstream-drm-nightly kernel and am running on stock:
chris@CKR-DKM:~$ uname -a
Linux CKR-DKM 3.19.0-30-generic #34-Ubuntu SMP Fri Oct 2 22:08:41 UTC
Christopher M. Penalver (penalvch), please let me know how long to test
upstream-drm-nightly before reporting-back and/or next steps.
Thank you for your assist.

Thank you. Christopher M. Penalver (penalvch) for your guidance. Please
see my findings with the upstream kernel, below:

Unfortunately, I hit the hard-stop(total freeze) within 2-minutes
of booting into the upstream kernel while I was editing this bug report.
Alas, I feel the need to mark it as existing in the upstream kernel.

OK,
I'm getting better results with the following settings:
ALREADY TRIED:
Disable VT-d(Intel Virtualization Technologies) in the BIOS
/etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"
then
$ sudo update-grub
and
/etc/modprobe.d/i915.conf:
options i915 semaphores
It is also recommended to _disable_ VT-d(Intel Virtualization
Technologies) in the BIOS when using:
i915_semaphores=1
boot option.
This increases the stability of the stack / system, according to Intel's
release notes for this option.
This fixed my DELL Inspiron 3646 using a J2900 cpu BayTrai
EDIT to #10:
ALSO: disable VTd(Intel Virtualization Technologies) in the BIOS for increased
stability

EDIT to #9:
Turns-out that a better solution to my issue is to leave intel_pstate
enabled(per default) and add:
i915_semaphores=1
to my kernel boot cmdline.
Working well so far.

[ WORKAROUND ] add intel_pstate=disable to boot cmdline:
$ cat /proc/cmdline
