That's very much appreciated. The point is that all vanilla kernels up 
to 2.6.20+ have not had the problems now seen on 2.6.20-rc1 and 
2.6.20-rc2 and like other problems reported, sic framebuffer, etc., 
there is a distinct likelihood that it's related to those kernels and 
worth reporting here where it will also be seen by the openSUSE kernel 
developers.
Regards
Sid.

No, that's what should be repeated:

# start round
cp /path/to/.config .
make oldconfig
make
# install kernel, check whether it's good or bad, then:
git bisect [bad|good]
# start next round

If I boot up on 2.6.20-git10 and run "git bisect bad", "git bisect good 
v2.6.20-git10" or "git bisect bad v2.6.20-git11", it says it's not a git 
repo.

I am still no clearer what's required.  If I do "cg-clone" I get 
2.6.21-rc5. The previous one got me 2.6.21-rc4.
The manpages and the tutorials I've looked at are quite cryptic and the 
commands do not produce the expected results.
As indicated above, I followed the instructions bullet by bullet without 
any clear understanding of the tools.
1) Ran the commands as above,cg-clone; git start; git bisect bad 
<checksum>;git bisect good <checksum of 2.6.20-git10 > I presume.
2) 2.6.20-git10 is the last good kernel.
3) 2.6.20-git11 and later are all bad.
4) I do cg-clone which gives a kernel whose Makefile is 2.6.21-rc4 (or 
whatever is current).
5) I get a kernel named 2.6.20-g208367e after make - rebooted and it 
fails the same way as 2.6.20-git11.
6) ran "git bisect bad".

Sounds right.

Someone else doing the bisect suggested that
0475ac0845f9295bc5f69af45f58dff2c104c8d1 is the problem commit.
Unfortunately I can't see anything wrong there.

Sid when you get that far if you can confirm or deny that
0475ac0845f9295bc5f69af45f58dff2c104c8d1 is the problem commit
I would appreciate the extra data point.  Having two people
report the problem at the exact same place would confirm for
me that we actually have a good trace, and that I really am
blind.

I think I got your problem:

After rebooting, you do "git bisect [bad|good]"  *once*.

Then recompile the kernel from the current tree, reboot, and again
*once* "git bisect [bad|good]".

etc.

This is the procedure I followed.

# install git and cogito on your computer

========================================================
I built and installed the kernel downloaded using "cg-clone", booted it 
up  and ran "git bisect bad".  I'm also somewhat confused as the first 
failing kernel is 2.6.20-git11, the Makefile says the kernel got with 
cg-clone is actually 2.6.21-rc4 and it built as  2.6.20-g208367ee.

I'm a little confused at what I am seeing below.
Normally what happens is that after a kernel compile and test.  You call
"git-bisect bad" or "git-bisect good" and then git-bisect picks the next
kernel to test.  Then you compile and test that one.  It looks like
you called git-bisect bad several times in a row without testing....

This is what I've got so far on the first boot, I shall have to check

[b7de8e7e3c7b79a72c20c7fd58bd65df3d146b13] ia64: fix noncoherent DMA API 
so devres builds

 # git bisect bad
b7de8e7e3c7b79a72c20c7fd58bd65df3d146b13 is first bad commit
commit b7de8e7e3c7b79a72c20c7fd58bd65df3d146b13
Author: Roland Dreier <rdreier@cisco.com>
Date:   Wed Feb 14 00:32:53 2007 -0800

    [PATCH] ia64: fix noncoherent DMA API so devres builds

    On ia64, drivers/base/dma-mapping.c doesn't build because it calls
    dma_alloc_noncoherent() and dma_free_noncoherent(), which appear to be
    terminally broken; the calls end up generating errors like

        drivers/base/dma-mapping.c: In function 'dmam_noncoherent_release':
        drivers/base/dma-mapping.c:32: error: 'struct 
ia64_machine_vector' has no member named 'platform_dma_free_coherent'

    because the multiple levels of macro expansion in 
<asm/dma-mapping.h> and
    <asm/machvec.h> end up turning a call to dma_free_noncoherent() into
    ia64_mv.platform_dma_free_coherent (instead of the intended
    ia64_mv.dma_free_coherent).

    This patch fixes this by converting dma_{alloc,free}_noncoherent() into
    inline functions that call the corresponding coherent functions, 
instead of
    trying to do this with macros.

I see this kwin bug too
on a Thinkpad (x86_64) as well as on a Pmac (powerpc64).
It is only triggerd when the screen is locked AND! set
to standby mode (display/backlight is turned off - acpi).

FWIW:
My standard instructions for users who are asked to bisect are [1]:


<--  snip  -->

# install git and cogito on your computer

# clone Linus' tree:
cg-clone \ 
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

# start bisecting:
cd linux-2.6
git bisect start
git bisect bad 86a71dbd3e81e8870d0f0e56b87875f57e58222b
git bisect good ac98695d6c1508b724f246f38ce57fb4e3cec356

# start round
cp /path/to/.config .
make oldconfig
make
# install kernel, check whether it's good or bad, then:
git bisect [bad|good]
# start next round


After at about 8 reboots, you'll have found the guilty commit
("...  is first bad commit").


More information on git bisecting:
  man git-bisect

There's not a lot of docs out there.

The man-page:  http://www.kernel.org/pub/software/scm/git/docs/git-bisect.html

Linus's email doc:
http://www.kernel.org/pub/software/scm/git/docs/howto/isolate-bugs-with-bisect.txt

I worked on something over last weekend, but it doesn't really add
much to the references above.

Did you tell git where to begin with good and bad?  I.e., you have
to tell it the bracketing of where to do the binary search.

git bisect between git10 (ac98695d6c1508b724f246f38ce57fb4e3cec356)
and git11 (86a71dbd3e81e8870d0f0e56b87875f57e58222b) is likely the most
productive thing that can be done right now.  

I can't think of anything in my sysctl patches that would kill an
application.  My sysctl work is right on the border with user space
so it is a good candidate but at the same time there should have
been no user visible changes.  There were a few places where
I removed sys_sysctl support (but not /proc/sys support) but I don't
think any of those were on x86, and they were is such a messed up
state I don't think anyone could have reasonably used them anyway.

So I think either we poke blindly making random guess by hand or
we let git-bisect do it.

Sid do you think you can figure out git-bisect?
git-bisect start
git-bisect bad 86a71dbd3e81e8870d0f0e56b87875f57e58222b
git-bisect good ac98695d6c1508b724f246f38ce57fb4e3cec356

It should narrow the problem down to a single commit in 6-8 tries
after which point we should have enough information to start
making intelligent guesses. 

Eric

Thanks for this search.

Looking at the changes between 2.6.20-git10 and 2.6.20-git11, the only 
suspicious changes are the 60 sysctl patches by Eric.

Eric, can you look at this issue?

       "Is there not promise of rain?" Ling Tan asked suddenly out
        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.

I tracked the problem down to 2.6.20-git11. Up to 2.6.20-git10 is OK, 
but from 2.6.20-git11 up to current 2.6.21-rc4-git2 all exhibit the problem.

Sid.

I shall go back to 2.6.20-git3 and work forward. Up to 2.6.20-git2 was OK.

2.6.20 worked.

2.6.20-rc2 did not.

Working theory: the kernel broke.

Sid, the chances that anyone can work out what caused this are pretty low. 
It would be great if you could perform a git bisection search sometime in
the next few weeks, work out which commit caused this.

Thanks.

 From kwin, the exit was caused by me doing CTRL-ALT-BKSPC after the 
kdeinit stuff had exited.

Oops!, above text should read the same as the subject line,  problems 
seen on 2.6.21-rc1 and 2.6.21-rc2.
The strace is huge 2737627 2007-03-02 03:28 KWIN.out.  Further digging 
shows kwin, kicker and klauncher and perhaps other kdeinit stuff also 
die - no desktop icons after those 3 are started from the commandline. 
Moving kdesktop_lock out of /opt/kde3/bin, everything comes back after 
the video is blanked -- no password required.
I shall run like that (2.6.21-rc2-git1 currently) and wait for openSUSE 
to upgrade to 2.6.21. I can send the straces of kicker and kwin on if 
you think it's still worth it.
Thanks and Regards
Sid.

Perhaps that line is never executed.

Try running kwin from your konsole after it dies, with the strace of 
course. Oh, and put the '-o ...' before the kwin command, not after.

This is the linux kernel mailing list. Perhaps you should post your problem to 
the opensuse mailing list.

openSUSE 10.3 Alpha and KDE-3.5.6, xorg-x11-7.2. KDE is setup not to
require a password to unlock, but it asks for password. When the screen
unlocks, kwin is gone with no errors logged in /var/log/kdm or
/var/log/messages. No problems with 2.6.20.

Same problem on openSUSE 10.2 x86_64, KDE-3.5.5 and 2.6.21-rc2.
Regards
Sid.
