Behavior:
Ever since I first installed 15.04 back in April/May on my new DELL Inspiron 3646:
Handle 0x0001, DMI type 1, 27 bytes System Information Manufacturer: Dell Inc. Product Name: Inspiron 3646
I have experienced frequent(daily/every-other-day)complete lockups(cannot even switch to console(Alt-F1,F2,etc.).
I have determined that the issue is related to the 'i915' driver in relation to my GPU:
00:02.0 VGA compatible controller: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display (rev 0e)

I have gained _significant_ improvements in reliability / stability by using various flags / parameters in the i915 module:
/etc/modprobe.d/i915.conf:
options i915 semaphores=1
and / or
/etc/default/grub:

Disable "Intel Virtualization Technologies" in the BIOS.
