I upgraded from a RedHat 9 to CentOS 4.1 system using yum without any hiccup. Upon reboot, the kernel appears to be stalled after printing this message: "Creating block devices". Keyboard is still responsive and you can press ALT-CTRL-DEL to reboot the system (when pressed, it says something about MD being unmounted). This is the last few lines before it hangs: Freeing unused kernel memory: 176k freed Rd Hat nash version 4.2.1.3 starting Mounted /proc/filesystem Mounting sysfs Loading jbd.ko module Loading ext3.ko module Creating block devices The kernel I'm using is the kernel-smp-2.6.9-11.EL.i686.rpm (I've also tried the uni processor kernel with the same result). What happens after creating block devices? Any idea what to look for/check? TIA!
