My HP6730B (x86_64 kernel, uptodate lubuntu Lucid installed) fails to suspend
on recent git kernels, the screen goes black (backlight on) and stays there forever.
Here's what I found from a bisect.
Alas reverting that single commit on current linux/master does not
solve the issue so it could be that I did something wrong... anyway
here the log of the bisect:

Does it work if you revert that commit?

I did bisect again and I did get a different result:

fatal: Commit c1518f12bab97a6d409a25aaccb02dc8895800f3 is a merge but no

How am I supposed to proceed now ? (sorry I'm a git newbie)

The bisect turned up a merge, which means it probably didn't really converge
for you.
Do you use a camera driver?

Yes, this laptop has an integrated webcam.
Bus 001 Device 004: ID 04f2:b059 Chicony Electronics Co., Ltd
which i think is driven by uvcvideo.ko. I've tryed to rmmod uvcvideo,
videodev and
v4l1_compat but on current git suspend still hangs in the same way
(screen black,
backlight on, fans at full speed, no response to ping and... nothing in
the logs).

Please try the current mainline with acpi_sleep=nonvs in the command line.

With:
acpi_sleep=nonvs console=tty0
(kubuntu defaults to quiet spash) I was able to complete 3 suspend/resume cycles before hitting an hang. After a power cycle I was able to suspend again, so it seems that, albeit racy, this cmdline has a positive effect.
With:
acpi_sleep=nonvs
or
console=tty0
alone I've never been able to suspend (only the combination of the two makes a difference).

Have you checked the thread started by Thomas Meyer :
2.6.35-rc6+: i915: Bisected regression
He describes something similar to your problem (and I was having the same),
and the solution he indicates worked for him, for me, and a third person so
far.
Regards,
Paul

Hello Roland,
I did reply on the same thread confirming that that's the same
issue I was having and that the proposed workaround did work for me.
After some days of testing I'm observing sporadic lockup on resume (not
in suspend as in my original report), but I think this is another issue.

Yes,
this seems to match pretty well.
Kind regards.
