Description Joël Tang 2012-04-15 12:59:48 EDT
Description of problem:

After the installation (and the post-configuration), when Fedora boots, it bugs often, by stopping on the starting up of Sendmail. Having removed Sendmail, the screen jams on the starting up of display manager (Gnome).

Version-Release number of selected component (if applicable):

Fedora 16.

How reproducible:

Just by rebooting.

Steps to Reproduce:
1. Install Fedora.
2. Configure Fedora.
3. Reboot.
Actual results:

The display manager seems to stop the booting. Fedora can't boot.

Expected results:

Fedora should boot.

Please provide the output of the boot when you add "systemd.log_level=debug systemd.log_target=kmsg" to the kernel cmdline.

Does this continue to boot if you wait 10min?

Are you sure it actually freezes during boot? If you press Enter, do you get a login prompt? Is there a login prompt on A-F2?
Comment 2 Joël Tang 2012-04-16 14:07:52 EDT
Sorry, I don't know what is the "kernel cmdline".

No, Fedora doesn't boot, but there is a login prompt on ALT+F2.
Comment 3 Lennart Poettering 2012-04-16 14:30:50 EDT
The kernel cmdline is the command line of the kernel. You can alter it in grub by editing the kernel you want to start.

If you log in on A-F2, can you paste what "systemctl list-jobs" and "systemctl status prefdm.service" say?
Comment 4 Joël Tang 2012-04-16 15:59:01 EDT
Apparently, the kernel cmdline changes nothing.

Concerning the commands :
- systemctl list-jobs : "0 jobs listed".
- systemctl status prefdm.service : I will submit an attachment.

Comment 6 Lennart Poettering 2012-04-16 16:44:52 EDT
Hmm, so gdm works fine, and no jobs are queued, so everything is is perfectly fine AFAICS.

Hmm, so can you explain again what exactly you think isn't working?
Comment 7 Joël Tang 2012-04-16 16:50:33 EDT
I do not know exactly, because I do a lot of things right after installation. Installing Flash can it affect this problem ?
Comment 8 Joël Tang 2012-04-16 16:54:48 EDT
I note that during the first round of updates, SELinux blocks access to /etc/ldconfig to /etc/shells.
Comment 9 Joël Tang 2012-04-16 20:19:34 EDT
New problem. After reinstalling Fedora, Xorg starts, but an error message appears : "Oh no! Something has gone wrong. A problem has occured and the system can't recover. Please contact a system administrator".

I think this bug doesn't exist with other graphic environments (XFCE, etc.). Only GNOME doesn't work.

Your system clock seems to be somewhat quirky.
And the output does not show any Xorg process, so it may be X that's having trouble starting. Check /var/log/Xorg.0.log for errors.

If the problem appears only after doing a lot of things, it is reasonable to assume one of the things causes it.
I don't know about Flash.

What is the hardware (especially the graphics card) in the machine? Do you 
install any 3rd party drivers?
Comment 11 Joël Tang 2012-04-17 08:38:13 EDT
I am not mistaken with time, which is normally synchronized via NTP.

I did not install 3rd party drivers. My GPU is an APU (CPU + GPU) : AMD A6-3650. I have already discussed my problem, it seems that my hardware is only compatible with VESA.
