Please attach dmesgs from both 3.6.x and 3.7-rcLatest.
What's the problem with bisection? If you can't continue because of build
error, please attach it too.

I hope ebb945a94bba2ce8dff7b0942ff2b3f2a52a0a69 is not a culprit... (146 files

--- Comment #3 from schaefer.frank@gmx.net  2012-11-15 14:59:45 ---
Concerning bisection problems:
Starting with commit 70ee6f1cd6911098ddd4c11ee21b69dbe51fb3f9 (the first
skipped commit), system starts up in VESA modes. Somewhere in the middle of
those 16 commits, it changes to a kernel panic (NULL pointer dereference) very
early during the boot process. No compilation problems.

The machine dies when hitting this bug wit 3.7, so no dmesg output is possible.
I can post the content of /var/log/messages, but there is nothing of interest.

I've updated to 3.7-rc5 of today and the first reboot the system started
normally (!). I was able to retrieve the dmesg output before the machine died
again after ~2 minutes (with the same garbled screen).
The next 5 reboots again failed on X-server start.

fix for bisection

Can you apply this one on top of 70ee6f1cd6911098ddd4c11ee21b69dbe51fb3f9 (the
first commit which fails), verify it helps, and continue with bisection?

Are you sure you that you attached the right patch ? Seems to be the same as
the last one...
Will test tomorrow.

--- Comment #17 from schaefer.frank@gmx.net  2012-11-17 15:24:48 ---
To make it short: please disregard comment #15. 
My original statement was right, 5787640db6ae722aeadb394d480c7ca21b603e34 is
the last good commit and 70ee6f1cd6911098ddd4c11ee21b69dbe51fb3f9 doesn't start
up.
No idea what went wrong yesterday, tripple-checked now.

I applied your patch on top of 70ee6f but it doesn't help.

UPDATE:
I've tested with 3.8.0-rc1, and now I have a good chance that the system
starts.
The criticial point is shortly before the the KDE Desktop appears (near the end
of the KDE startup progress screen). If it survives this point, the machine
runs stable for hours.

Maybe this gives us a hint of what could be going on ?
Could this have something to do with memory allocation ? Remember that this is
an onboard device using a part of the systems RAM.

I am hitting a bug with very similar symptoms, probably the same bug. Reported
at https://bugs.freedesktop.org/show_bug.cgi?id=61321 with bisection also
pointing to 70ee6f1 as the first bad commit.

I see next trivial (but interesting to me) differences in same case:

Older (good) kernels show messages on boot:
[    0.898887] [drm] nouveau 0000:00:0d.0: ======= misaligned reg 0x0060081D
=======
[    0.898919] [drm] nouveau 0000:00:0d.0: ======= misaligned reg 0x0060081D
=======

New (broken) kernels - no. Even I do not find (fast search, sorry) even near
similar code in nouveau_bios.c.

PS In my case (Gentoo, openbox, tint2, feh - minimalistic) I have sure hang
(broken screen and no messages) on mozilla's start (own build seamonkey with
very forces GL usage) and IMHO mplayer/xv (but times ago, unsure). Other cases
not checked, but at least Gtk+ (in xfce's Terminal) is stable.

That's a separate issue and has nothing to do with this bug.
See https://bugs.freedesktop.org/show_bug.cgi?id=47182
In most cases, it is no bug at all.

OK, I just suggested since new DRI code not detect this misalignment - it can
be sources of this bug, this is just visual differences.

This is -still- an issue for all kernels >= 3.7. Only kernels up to 3.6.x avoid
the locking issue which makes the later ones unusable on systems with this
video device, here an on-board nVidia Corporation C61 [GeForce 6100 nForce 405]
(rev a2).

This still affects 3.9.9 from fedora 19.


$ lspci -nn | grep VGA
00:0d.0 VGA compatible controller [0300]: nVidia Corporation C61 [GeForce
6150SE nForce 430] [10de:03d0] (rev a2)

Indeed, all kernels > 3.6 are unusable. sooner or later the system freezes.

Created attachment 131911
  --> https://bugzilla.kernel.org/attachment.cgi?id=131911&action=edit
patch: port from <3.7

Try this patch. I have some happy uptime (I have this Gigabyte mb on work
desktop and use 3.4 before), but this bug can be too unpredictable. This is
port of similar aligning from <3.7, just minimized. Also I don't move
"misaligned reg" warning, as nobody cares from 2012. I copy old notes in
comments, so you can find original similar places (was: if (reg & 0x1)
reg&=...) by this comments.
