months ago a regression was introduced which now causes it to hang on suspend.)
It may be worth backporting this fix to Lucid (although I

I have some pretty bad news
First, the bad commit seemed incorrect since it related to ath9k instead
of iwlagn (I don't use ath9k).
I tried with both 3.0.0-8.10 and your 3.0.0-8.10+lp811214v1 and both
failed.
I went back to the latest good kernel, and I tried suspending twice, and
it failed
Thanks Loïc. I have to agree that I was getting mighty skeptical as the
bisect got narrower and saw it converging on ath9k.
Anyways, let us know if you're able to determine a reliable reproducer.
You might want to also ping Colin King (cking) about his systemtap
scripts for debugging
So I've started from a plain natty debootstrap + grub + linux kernels +
pm-utils + wireless-tools of USB
I did the same sequence starting with 2.6.39 (good) vs. 3.0-rc1 (bad)
and confirmed most tests above with one failed suspend with expected
blinking suspend light for each bad commit and 3

Hi Loic,
So lets start this bisect.. I'll apologize in advance about the number
of test kernels you'll have to go through. Bisecting between a major
version jump is the most painful and will take 10+ iterations I'm
guessing.
First, I'd really like to eliminate the possibility that this was
I'd love if you could help me on this, thanks! I think I know how to
run git bisect, but because the history has been rebased between

think.
If you have some test kernels, I'd be happy to try them out

Hi Loic,
I'd be willing to help you with the bisect (ie build some test kernels
for you) to really narrow down the bad commit between 2.6.39 and 3.0. Or
if you're up to it, you could follow the ubuntu dev week talk that John
