Bug 598613

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command (or if the system is really frozen then at least /var/log/dmesg after the restart), and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Sorry for late reply, I was unable to access the device for the last weeks.

All logs are as of last boot as the system really crashes when connecting an external display. I even ran "tail -f /var/log/messages" via SSH before and while connecting but the system simply dies and no further messages appear.

Before testing, I updated to all current packages using yum update.

I can confirm that issue on an I5 with Fedora 14, I'll try to gather an oops via serial ASAP

Waiting on it then.

Totally forgot about it (will try to reproduce it later), anyway it seems to work on 2.6.35.6-48.fc14.x86_64

Reporter, do you agree? Is the bug fixed with this version of kernel?

Thank you

I am sorry, but my computer still runs F13, so I am unable to contribute any information on F14 kernels at the moment.

As I failed to set up a serial console, I've tried with netconsole and got this:

As a side note: the process doesn't even react to kill signal...

I believe I am affected by the same bug although using different hardware (Dell Latitude E6410 with an simple E-port station, see attached lspci output) with an up-to-date (but this behaviour is not new) Fedora 14.  Following are the attachments which were asked to the submitter.

Note that there are several occurrences of the bug in there.

This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. 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Fedora's policy to close all bug reports from releases that are no 
longer maintained.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 '14' 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 14 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:
