Nouveau - Jan 2010 - [Bug 26321] New: [9400M] GPU lockup and X does not start

http://bugs.freedesktop.org/show_bug.cgi?id=26321

           Summary: [9400M] GPU lockup and X does not start
           Product: xorg
           Version: git
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: johannesobermayr at gmx.de
         QAContact: xorg-team at lists.x.org

dmesg

With latest code (KMS, libdrm, Mesa, nouveau) I have a GPU lockup and X does
not start.

Commit eeec3a1ecd703d3a32fe223274d2a77686030d78 worked on 2.6.32.

Btw. nouveau/linux-2.6 does not compile on 2.6.33-rc5. You have to
"patch" so:

On linus tree:
git archive tags/v2.6.33-rc5 drivers/gpu include/drm ...
(git archive master ... does not compile)

On nouveau/linux-2.6 tree:
git archive master drivers/gpu/drm/nouveau include/drm/*nouveau* ...

Then "patch" contents of linus tree archive with contents of
nouveau/linux-2.6
tree ...

It compiles now ...

(Maybe this "patch" is related to the GPU lockup ...)

dmesg | grep drm with drm.debug=6

When starting X I can connect via SSH but nothing else works (like keyboard,
power button). Only reset button works and I can also reboot system via SSH
(execute "reboot" twice) ...

X looks like this:

dmesg with drm.debug=6 is attached.

Xorg.0.log is not really changed (only time/date).

startx -- -verbose 6 -logverbose 6 2> startx.log provides only an empty file.
(Is this command obsolete?)

But I can provide a gdb - bt full attached to /usr/bin/Xorg ...

Please retry with the current nouveau kernel git, this should be fixed.
