suspend issue

[Justin Mattock]

Hello; I seem to have discovered something with echo mem > /sys/power/state.
I recompile the kernel and had forgotten to compile fglrx, when
performing a suspend without fglrx I was confronted with the dreaded
blank screen and a reboot. then as a test I compiled fglrx and loaded,
and to my amazement suspend reacted properly again.

Yeah, but I it does not even work without X - console only!

s2ram -f -p used to work since at least 2.6.20 ... and is now not
anymore in 2.6.25-*

Yeah; that's what I was contemplating as well.

Dave, has anything changed in the video/graphics department that might
cause that to happen?

First, please don't top post.  Looking at this message you can see why it
really doesn't make sense. :-)

Now, in short, to run a git bisection:

(1) clone the Linus' tree (see http://linux.yyz.us/git-howto.html#download_first_time)
(2) from within the kernel source code directory downloaded in (1) run
	$ git bisect start
	$ git bisect bad
    (this will mark the last revision as a failing one)
(3) If you have already verified that 2.6.24 works correctly, run
	$ git bisect good v2.6.24
    (this will mark the 2.6.24 kernel as a good one)
(4) as a result of this, git will select a kernel revision between 2.6.24 and
    the most recent one for testing.  Compile it, install it and check if it
    works.  If it does, run
	$ git bisect good
    Otherwise, run
	$ git bisect bad
(5) repeat (4) until there's no more revisions to test.

If you encounter any problems, please ask what to do next.

Thanks,
Rafael

This looks like bug #10319.  Can you please add yourself to the CC list in

I just tried, and the problem is that 25-rc1 already fails to suspend -
so I am not sure how I could get more insight into this failure *on
resume*... any ideas?

Argh!

Re: suspend issue

[Justin Mattock]

First how do I not top message?,
For the situation with suspend I was able to succeed when fglrx was
loaded(not sure about radeonhd)
In what I experienced over here: when not loading fglrx would cause my
system to recover from suspend with a blank screen then a reboot a few
seconds later. Now two days ago I upgraded Xorg to 7.3 then doing the
same test leaves me with a different result;
With having fglrx not loaded the system will recover from suspend, but
with a blank screen and no reboot a few seconds later.
I have not upgraded the opengl drivers yet. From what I can see over
here the kernel is probably O.K. This looks more like a module issue
opengl, fglrx, radeonhd etc...of the three fglrx is recovering(I
havent tried radeonhd) I will look into upgrading my opengl stuff
today  and test to see if they recover from a suspend.

Well, 2.6.20 worked, so bisect should be easy, right?

Using git is all new to me, so learning how to do a bisect, is
probably not a bad idea.

I don't quite understand... 2.6.24 worked yes, but 2.6.25-rc1 didn't
even *suspend*. However the problem lies not in suspending but no
display on *resume*. So the bug is hidden by the hang on suspend and I
don't see how I can check when resume broke.

Do you think the problem may be with the xserver? Did you upgrade to 7.3?
Over here I did the upgrade to 7.3, but with testing with vesa there
seems to be no module with the xserver for vesa
or at least I haven't located it yet. On a positive note suspend does
work with the ati driver installer, the negative side is
it doesn't work without it. So from my perspective over here, Does
xserver(7.3) have vesa support?
