Kernel 2.6.18-308.8.2.el5
I recently experienced an odd problem with a host at our warm-site location. The facility we use suffered an hvac failure during elevated ambient temperatures (30C+) on Monday past and the equipment room reportedly cooked for some hours. It was sufficient that our equipment shutdown. In all probability this was due to an over-temp condition since the systems are all powered from a UPS but possibly there was an extended power out instead.
Whatever the cause one of our hosts did not restart subsequent to this shutdown. Which condition required my presence on site. When it was powered up today in situ the host's console would display the CentOS splash screen with the message [press any key to enter menu] and then the message "Booting in ....4 seconds"
However, the countdown timer never changed from the initial value and the restart never took place. When I entered the console menu and selected the most recent kernel available the system booted normally.
<snip> I had that happen on one or two machines in the past, and never got it to go. I believe that eventually, one upgrade or another, fixed it. You might try yum reinstalling the new kernel, and redoing the grub-install, and see if that helps.
