For this matter, I have had success with WORKAROUND-2, and thus I am able to keep my lock screen on suspend. Not bullettproof, but I rarely get suspend hangs now. Do notice that since the time of this bug report, there have been several kernel updates, so that might also matter. To determine if that is the case, I'd have to run without any workarounds for a while and look out for new hang incidents. Have you experienced the suspend hang with the latest 14.04-kernel in -updates (kernel 3.13.0-36.63) ? Slightly off topic, but: Yeah, the current BIOS on this Dell model is obviously buggy. I did send a complaint to Dell support. The support case was closed after some dialogue (I ended up downgrading to BIOS A08), but I hope they forwarded the technical matters to the right people and that a future BIOS version will have more fixes for both keyboard, touchpad and suspend/resume.

(Airflow was not the best, since it was in a bag.) WORKAROUND: Hangs do not occur if the lock screen is disabled at suspend. WORKAROUND 2: Make pm-utils switch to console before suspend (and back after resume).
