Normally the kernel is excluded from automatic updates so I would say that it is unlikely to have been an automatically installed kernel that has caused this. The file /etc/sysconfig/yum-autoupdate has an setting for controlling automatic updates, and it also has the setting for which RPMs are excluded from being automatically updated. I would check this file and the yum.log to further investigate. And, as Connie suggested, you should be able to boot from an older kernel at the grub menu. -- Mark Whidby Infrastructure Coordinator (Unix) Physics/Chemistry/EAES/Mathematics Team IT Services, Faculty of Engineering and Physical Sciences
