Output of dmesg

Description of problem:
Computing checksum of EDID for my monitors fail and wrong resolution is set (1152x864 is set, 1280x1024 is maximum available and native resolution for my displays are 1600x1200). I have two same 20" LCD monitors Dell 2007FP, both connected via DVI.

It works fine with F14, after update (via yum) to current F15 it fails. If I add new mode for xrandr with info from Modeline from Xorg.0.log and use it, correct resolution works.

Version-Release number of selected component (if applicable):
kernel-2.6.38-1.fc15.x86_64
xorg-x11-drv-nouveau-0.0.16-23.20110303git92db2bc.fc15.x86_64


How reproducible:
Just start the system and X.

Actual results:
Wrong resolution is set.

Expected results:
Correct resolution is set.

Comment 3 Fedora End Of Life 2012-08-07 15:33:28 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
