Hi, 
with last kernel 3.x I have a segfault of X server (v. 1.13.0).
When i start X (on kde4 or gnome3 environment) all start correctly. I have a
CRT monitor that support 1600x1200 resolution. Through these steps i have
always segfault:
1. X started with a resolution of 1600x1200
2. Change resolution to 1280x1024 (here resolution change correctly)
3. Change resolution to 1600x1200 (here Segfault)

resize called 1600 1200
resize called 1280 1024
resize called 1600 1200

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

Same segfault happens if I leave my computer on poweron but with monitor on
poweroff. When i poweron monitor screen resolution automatically go to 1024x768
and then when i try to restore 1600x1200 resolution I have same segfault.

Hereinafter same informations about my env:

# uname -a
Linux golia2 3.6.0-rc6+ #1 SMP PREEMPT Sat Sep 29 11:29:58 CEST 2012 x86_64
Pentium(R) Dual-Core CPU E5200 @ 2.50GHz GenuineIntel GNU/Linux

# lspci | grep VGA  
01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce GTS 250]
(rev a2)

Mesa-9.0 and libdrm 2.4.39.

This error happens with both vanilla kernel or nouveau-kernel from git.

How can i help you to fix this bug ?

With gdb problem is happens after 5/6 resolutions change (I thinks that could
be relative to a delay required on driver to do this syscall).
However, after these resize this is gdb backtrace:

It looks more like xserver bug. Because of zero appearance of Nouveau in the
callchain it's not certain you are using Nouveau...
Please follow instructions from
http://nouveau.freedesktop.org/wiki/Bugs#HowToReport and attach dmesg and xorg
logs.

Hi,

I confirm that with xorg-server-1.12.4 this doesn't happens.
I move bug to Server/Acceleration/EXA.

Thanks for reply.

Bye

--- Comment #6 from Ge@@ru <geaaru-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> ---
Hi, i do other test about this problem and I found that problem is relative to
kernel nouveau driver and not to X.

I test this with different xorg-server versions:
- 1.12.4,
- 1.13.0
- 1.13.1 (current installed version)

and with xf86-video-nouveau:

- 1.0.1
- 1.0.2
- 1.0.3
- 1.0.4

and with different kernel:

- 3.7.0
- 3.6.8
- 3.6.4
- 3.5.7
- 3.4.24
- 3.2.35
- 3.0.17

With my test i see that only with 3.0.17 and 3.2.35 all works fine.

I'm sure that problems is on kernel driver.

Are there big changes between 3.2.35 and > 3.4 for nouveau kernel driver ?

I move this bug again to nouveau/driver but I'm not sure that is right. Sorry
if is wrong.

Thanks

Can you confirm whether this still happens with the latest
kernel/xf86-video-nouveau/Xorg? If so, please provide a complete dmesg and
Xorg.0.log after the issue happens.

Sorry for delay.

I test with last driver and seems that segfault doesn't happens. But I see that
resolution change automatically if a leave screen off. But probably could be
relative to a wrong EDID message from my old CRT monitor.
So, we can consider resolved this issue.

Thank you very much for support.
