Bug Description
I have Lenovo X200 laptop. In 11.04, it suspended & resumed reliably.
For the last week or so, running oneiric, the laptop has not suspended reliably. Specifically, when I suspend it for the second time, it starts to suspend – moon LED flashes, screen switches to black, blank terminal with a single non-flashing cursor – but never completes suspending. I inevitably end up having to force power-off by holding down the power button.
I asked on #ubuntu+1, #ubuntu-devel and #ubuntu-uk on how to report this effectively. The "best" help I got was someone telling me to try from unity2d to see if it's a compiz bug. I have the same problem under unity2d. My advisor told me to log it as a linux bug.

Hi Jonathan,
Can you tell me the most recent Oneiric kernel where suspend/resume was working reliably? Given you said it's been about a week since you first started noticing this, I'm guessing the 3.0.0-8.11 or 3.0.0-9.12 kernels were working for you? Please confirm as it will help us narrow down the window of regression and which patches to examine. Thanks in advance.
