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.

Description Rik van Riel 2012-04-20 18:51:25 UTC
Description of problem:

I run RHEL6 on a test machine with an old nvidia video card. When doing a certain thing (see below), Xorg will hang. Not only that, but Xorg will hang in an unkillable way, where not even SIGKILL can make X exit. At that point a reboot of the system is required to get X to restart...

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

kernel 2.6.32-262.el6.x86_64

04:04.0 VGA compatible controller: nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro] (rev 15)

Steps to Reproduce:
1. start virt-manager
2. from the "view" menu, select the option to scale the guest display size to the window size
3. resize the guest window
  
Actual results:

Xorg hangs, and is not killable even with SIGKILL. I see this in dmesg:

Expected results:

Ideally things would just work. I understand this particular hardware may be too old to bother supporting, but it would still be nice for the nouveau driver to be robust against random failures.
