Comment 7 for bug 1250476

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
