RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

backtrace from gdb
Comment 5 Lubos Kocman 2011-03-17 21:56:12 UTC 
100% percently reproducible on my setup. Happens immediately or after next refresh of the page.

I'd like to mention that the attached plugin is 64bit flash player square.

Anyway don't blame Mozilla plugin for Crashing Xorg
Comment 7 Lubos Kocman 2011-03-17 22:34:02 UTC 
Does not seem to be actually very specific ... I just tried few other youtube vids and I got the same result.
Comment 8 Matěj Cepl 2011-03-17 23:32:49 UTC 
Could we get also output of dmesg and /var/log/messages AFTER the crash but before reboot, please? I don't see anything interesting in the /var/log/Xorg.0.log.
