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 of problem:

Machine randomly hard locks, mouse / keyboard inputs no longer work (Unable to switch VTs, etc). Hard reset is only way to recover.

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


How reproducible: 

Random, could happen within 15 minutes of boot or 10 hours; however, seems to happen most when in a browser, Chrome / Firefox.

Steps to Reproduce:
1. Browse the web with chrome / firefox

Actual results:

Machine hard locks and only recoverable via a hard reset

Expected results:

No lock.

Additional info:

Just before the lock, the following is output in /var/log/messages:

Switching to proprietary nvidia driver resolves the issue

Comment 2 Louis Santillan 2017-09-24 23:18:54 UTC
I'm getting this super frequently as well (2-10 times per day!).  I'd switch to the proprietary nvidia (which fixes it for me as well) but then gnome doesn't know how to handle driving 3 video cards with windows.  The nvidia driver makes them available (I mouse over and the old X11 disabled screen pointer) but gnome seems to refuse to put windows on them.
