Hardware name: MSI MS-7817/CSM-B85M-E45 (MS-7817), BIOS V10.8 12/11/2014 Haswell chipset. S4 resume works fine (multiple times) on 3.19.0+ (git 89271faca1..) under load while compiling a kernel on 4 cores. Upgraded to 4.2.0 (see kernel version) to test compatibility of i915 with current kernel. Sleep mode worked fine, but suspend and subsequent resume results in Oops: [ 179.204936] PM: Syncing filesystems ... done. [ 179.207302] Freezing user space processes ...

Not directly reproducable with git checkout as of #201507220314. However, twice in ten suspend/resume cycles the system froze after resuming and displaying the login screen (X, Ubuntu 14.04). Even netconsole did not show any output (other than the messages that it always shows during boot) so I cannot say whether it was the same problem.
