           Summary: nouveau freeze Xorg on NV34
           Product: xorg
           Version: git
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: drdarkraven-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


The bug was first sighted when resize a 'fake transparent' rxvt window.
This action freeze Xorg.
And with some further investigation, I discovered that the bug is reproducible
by running:
 x11perf -compwinwin500
(And it's fine when running x11perf -putimage500)

And not only Xorg is frozen,it seems the whole system is frozen,too.
The cursor can't be moved,and ssh connection is lost.

I'm using a snapshot kernel,the bug appeared after I updated my kernel tree at
Aug 7.
And there is no such bug in nouveau kernel tree.

Here is my kernel log output.

Curious behavior of nouveau driver(though I don't know if it's connect with
this problem):
Once nouveau driver is loaded,after the screen resolution changed(which is
normal),there is a area,about 640*480 in size,at the top-left corner of the
screen,is totally white.

This behavior started maybe after 2.6.36-rc1

That's an unrelated issue, it's already fixed in Andrew Morton's -mm tree,
commit "vt: fix console corruption on driver hand-over".

Ben may have fixed this with e644bb2066cc46c01e5f8902bf840f19e1f942c6, could
you try again with latest git?

Yeah, I didn't expect my earlier fix to fix this or the other issues that have
been reported.  They fix another issue I encountered however.  I have been
unable to reproduce these so far, but my kernel has additional changes which
could possible effect things, I will try in more depth tomorrow.

You could try to build a kernel with CONFIG_LOCKUP_DETECTOR enabled. The lockup
detector logs a backtrace when the kernel stays stuck for a minute or so. It
may be useful along with a serial/netconsole to track this problem down.

The all-is-frozen situation described in the comment only appeared once.
During my bisecting,while Xorg is frozen,I'm still able to move mouse and
network is still working.
So according to the definition of 'Hardlockups':
  Hardlockups are bugs that cause the CPU to loop in kernel mode
  for more than 60 seconds, without letting other interrupts have a
  chance to run.
I don't think this is a hardlockup.

Ah! Then CONFIG_DETECT_HUNG_TASK would be more appropriate.

Actually if it were some kind of kernel deadlock you wouldn't be able to move
the mouse at all. Most likely the card has locked up for some reason, can you
reboot with "drm.debug=3 log_buf_len=256k" in the kernel command line and
attach new kernel logs after the hang?

FYI,commit 58374713c9dfb4d231f8c56cac089f6fbdedc2ec changed lock_kernel() and
unlock_kernel() before and after the func() call to mutex_lock() and
mutex_unlock().

It looks like fallout from an earlier problem, so yeah, full kernel logs would
be interesting.

So you claim there are no errors there? Please, provide *full* kernel logs.

BTW, can you reproduce this with the 3D drivers uninstalled?

Full kernel log here (too large for bugzilla):
http://pastebin.com/5TKurz6u

And I can reproduce it without 3D driver (completely without
3D,nouveau_dri,libGL & mesa uninstalled)

Most likely this is a race between the X server thread and the TTM delayed work
queue. It couldn't happen before because taking the BKL disables preemption.
Are you still in time to test patches?

I've been having similar freezes with NV34 while using very recent kernels, so
I would be very happy to test patches.

I'm using the nouveau support in Linus.git kernel, though, not nouveau.git.  I
could start using nouveau.git if that's what you'd be creating patches from.

Yeah, you could apply it over Linus' tree, if you want, but it has already been
reported to solve the problem.

Today's kernel from Linus seems to fix the problem for me too, fingers crossed.

The bug may be closed, but the dumb questions linger on forever :p

Yesterday I noticed a very similar hang on my NV4 machine (which I didn't see
before yesterday).

Does it make sense that this same bug would also affect an NV4 chipset?  Or
should I start thinking about filing a different bug report?

Many thanks!

Yeah it's probably the same issue, this bug affected the whole card range.
