I'm having constant problems with RHEL recently. My desktop crashes during the day occasionally (once a day roughly) and is hung (black screen) every morning requiring a button-hitting restart.
Clicking the "kernel crash dumps" menu item does nothing. I'm wondering if it's to do with the latest round of redhat updates but I don't want to just unwind updates on mere suspicion.
Anybody else hating Red Hat this week? How can I view the crash dumps?
