Second question: How do you turn automatic updates OFF.
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.
This is true if yum-autoupdate is installed and being used for automatic
updates. However, it's also possible to have updates enabled via
yum-cron (particularly in the case of earlier systems upgraded to SL6),
in which case the above won't apply.
In addition to controlling whether or not the update kernels are
actually installed, you can also control whether or not they'll be set
as the default kernel. You can do that by changing the value of
UPDATEDEFAULT in the /etc/sysconfig/kernel file. (I find this is a good
safety feature, in any case, particularly on systems where kernel
updates can break things. You can still install the update, but you're
in full, manual control of if/when that new kernel gets booted.)
