Summary0006301: Upgrade to 6.4 failed
DescriptionUpgrade to 6.4 caused my CentOs to block and never boot.
Steps To Reproduce1. I have the latest CentOs 6.3 release.

2. I issued "yum update" through the command-line and the update was successful.

3. I rebooted the machine.

4. The machine blocks and CentOs never loads.
Additional InformationI tried shutting down the machine and starting again. Same issue.

I attached a screenshot where the block happens.
TagsNo tags attached.

That's not really helpful (the screenshot). If you press ESC when this screen comes up first, you can see which services are started.

Indeed, the boot hangs at "Starting jexec services". It doesn't show "fail" or "success", it just hangs there infinitely.

Alternatively, I tried booting to the CLI and disabled the jexec service by running "chkconfig jexec off". I booted again to CentOs and it still hangs but at at the same place (the difference is "Starting jexec services" is no longer displayed).

So the question would be: What comes after jexec (or atd)? Is there anything to be found on one of the other virtual consoles (you can reach them with CTRL-ALT-F2 to F7)?

Hi range,

Thanks for taking the time for this. The other virtual consoles are accessible. I attached the screenshot of running the command "startx" in one of those consoles. How do I go about copying the content of a file? (I think the log file can give you more hints).

try to reinstall graphics card drivers

or delete /etc/X11/xorg.conf and it should start without graphics card acceleration

Hi czipis,

That did it (removing the conf file). Thank you!
