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.

Xorg.log

Description of problem:
Xorg server crashes when switching to console by Ctrl+Alt+Fn shortcut on i386 guest. It does occur always when doing the switching first time after boot, after crash It does not occur on all guests always. Xorg.log in attachment. We had this problem some time ago and It was fixed that's why I consider it to be regression.

Version-Release number of selected component (if applicable):
xorg-x11-drv-qxl-0.0.14-10.el6.i686
Linux Guest - Linux localhost.localdomain 2.6.32-211.el6.i686 #1 SMP Tue Oct 18 15:55:38 EDT 2011 i686 i686 i386 GNU/Linux
spice-vdagent-0.8.1-2.el6.i686

How reproducible:
Always

Steps to Reproduce:
1. Connect with spice client to a Linux guest after booting the guest
2. Press Ctrl+Alt+Fn to switch into console.
  
Actual results:
Segfault

Expected results:
No segfault

Additional info:
On x86_64 I am not able to reproduce so far.

Comment 2 Christophe Fergeau 2012-02-28 10:30:53 UTC
Here are some more details about how to reproduce (I have only asked some clarifications on IRC, I haven't tried to reproduce this)

1. start a linux guest
2. connect to it with spicec on a linux client
3. switch to a VT in the guest by pressing Ctrl+Alt+Fn (press Alt for a few seconds so that it sticks, and then press Ctrl+Fn)

Result: x.org on the guest segfaults
Expected result: no segfaults

Comment 4 Marko Myllynen 2012-09-10 15:00:11 UTC
I'm seeing the same problem on RHEL 6.3 + latest errata on x86_64. After booting up the guest and switching to a console X starts crashing constantly.

I'll attach Xorg.log with the xorg nevr's appended.

Thanks.

Thanks a lot for the pointer, I've rebuilt xorg-x11-drv-qxl-0.0.14-13.el6_2 with the patch and it fixed this issue.
