[Bug 1274471] Re: S3 Failures on certain Dell Haswell systems with 3.11 and 3.13 Kernels
Also 3.11.10.3 fails on the 9020.
However kernels after that (3.12+) appear to work on the 9020, i'm not clear whether the failure w/ 3.13-rc8 was only observed on laptop HSW hardware.
So at least on the desktop HW it's somewhere between 3.10 and 3.11 that the failure was introduced and somewhere between 3.11 and 3.12 it was fixed (but not in any 3.11 point releases).

Title:
S3 Failures on certain Dell Haswell systems with 3.11 and 3.13 Kernels
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Dell has reported that certain models of their Haswell-based systems
have been having issues with S3, starting with the 3.11 kernels in
13.10.
Here are some data points for now:
1) Doesn't happen on ubuntu or debian with 3.7
2) Doesn't happen on 13.04 with stock 3.8 kernel
3) Happens on stock kernel for 13.10
4) Happens on 3.13-rc8
5) Specific to Dell HSW HW. Not happening on other OEM HSW HW from what has been reported.
Business-Client machines (such as Optiplex, Latitiude, etc) seem to
reproduce the issue, but, systems like the XPS 13 with Haswell do not.
Some tests are being run on an Optiplex 9020 to try and narrow down
what exactly might be wrong.
