Re: [CentOS] Uniprocessor kernel booted after YUM update

Recently, yum installed an updated kernel 2.4.21-32.0.1.ELsmp; when we got around to rebooting, we found that some of the machines were running the uniprocessor kernel 2.4.21-32.0.1.EL , showing only a single cpu. The grub.conf file had been modified in the usual pushdown manner but the default kernel had been set at #2 instead of #0.

I had an extremely similar thing happen to me on a RHEL3 box when I applied update 5. I didn't notice it for a few days so I just assumed I had made a mistake, but your post inclines me to believe its a bug in the upgrade scripts.
