the patch attached to the bug report
makes my machine boot up with out a
Panic, and allows me to do remote debugging
via ohci1394_dma.

I did see a call trace as I was debugging
which might be related to having one
system using the patch, and the other not.
but still need to look at that.
(only saw this once out of numerous boots
(could be a rarity)).

The current 2.6.33-rc7 has a much more worse behaviour. With the previuos
series I could (sometimes) put the ThinkPAd into the docking station again
(after wakeup) and the external screen shows the X11 screen or at least I
could press Ctr-Alt-Backspace and restart the X11 server. The current -rc7
however is balck, don't accept after wakeup key nor mouse nor any SysRQ
keyboard sequence.

It looks like we should revert this commit, seems broken.

Anyway, I'll do my best to have a look at this bug later today.

I wonder if the patch from http://bugzilla.kernel.org/show_bug.cgi?id=15000

In such case I'd prefer to add "broken_DOS" flag for devices that were
enabled by this patch. We could avoid restoring backlight on resume
for broken_DOS then and maybe just update brightness to current value.

Hm, otoh we had definitely people with some Asus laptops who where only be able
to use backlight control with it. So I would rather prefer some work around to
the suspend/resume problem (_DOS if I understood correctly).

It's same case with my Sony VAIO. Without this I can not control
backlight. Eventually I can hack on GPU registers directly, but I
don't think it can be called solution.

No, tested patch against 2.6.32.8-rc2 and current git (-rc7) - no success.

BTW the mentioned commit fe06fba29 of bug #15000 is 1 month younger than the
first bad commit c1c7af608 of bug #15100.

Well, do I understand correctly that without commit
3a1151e3f124fd1a2c54b8153f510f1a7c715369 you can't control the backlight,
but with the commit applied there's a resume problem on your box?

Or perhaps we can try to restore the backlight at a different place.

I wanted to find out what causes this lock up by syncing modules
resume or putting some delays. See bug report of my question.
Unfortunately didn't get answer.

That's right.
BEFORE: no backlight controll, resume works fine
AFTER: backlight control, resume locks up machine

Rafał can correct me. I would phrase it that way that without the bisected
patch, there is no backlight control. And because there is with it, we hit the
next BIOS bug because the backlight driver now tries to correctly bring it back
on resume.

Do you suspect some conflict between video module and BIOS? Any more ideas?

That would be my guess based on the (admitted not to be very deep reading across
some of your and Rui's comments. He probably has a better Idea on that. But what
the patch in question does is to allow video devices that have not all the
methods defined (before _DOD *and* _DOS, after _DOD *or* _DOS) to be handled by
the generic acpi video driver. And this gets you backlight control (by some
additional methods). But now, as the driver is in use, it is in the
suspend/resume path and this causes problems.
>From cross reading bugmail I had the feeling Rui was on a track while I did not
follow close enough to take in any details.
I would suspect that code assumes details from those two (_DOD and _DOS which is
not there if the BIOS provides them both and is not handled as the driver used
to be only used in that case). I probably should get back and read the bug
report with all the info in detail somewhen tomorrow.

Hmm.

I think the Jérôme's comment at

http://bugzilla.kernel.org/show_bug.cgi?id=15096#c19

is actually correct. It looks like acpi_video_resume() is executed before the
KMS driver's resume and things go south.

In fact, we seem to have a design issue with acpi_video_resume(), because it's
called too early.
