[James Hewitt <1250476@xxxxxxxxxxxxxxxxxx>]

I had a look at the e1000e driver and tried a new version of that, so I
installed a new version of that. It suspended fine today (in
circumstances that have previously caused a problem). I'll run like this
for a week before updating the bios. I think its version 2.3.2 in saucy,
not sure why it would be so far backlevel, there is also a 2.5.4 stable
version.

jammy@pk0k4dr:~$ sudo ethtool -i eth0
driver: e1000e
version: 2.4.14-NAPI
firmware-version: 0.13-3

There are a few power related changes:
* Upstream - commit e60b22c5b7e59db09a7c9490b1e132c7e49ae904 (e1000e: fix accessing to suspended device)
* Upstream - commit 66148babe728f3e00e13c56f6b0ecf325abd80da (e1000e: fix runtime power management transitions)
* Cleanup/refactor - Runtime Power Management flow
* Refactor/fix system hibernate flow

Title:
  8086:1502 [Lenovo ThinkPad W530] e1000e module sometimes prevents
  suspend to ram

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Sometimes, usually towards the end of the day, I find my e100e module
  does not allow the system to suspend.

  WORKAROUND: "rmmod e100e" and I can suspend again. I do use the
  ethernet adapter, and it only has occurred after having been connected
  to ethernet.
