I'm running CentOS (Rocks 4.1) on a Compaq Presario.
This machine boots fine from a cold start but won't reboot. I know the cpu is posting because I can see the cdrom light and hdd light go on briefly, I presume, looking for a bootable partition. My /boot is a subdirectory of /, which is an efs3 partition on a SATA drive.
I don't know if this is relevant, but I don't see an e3fs_stage1_5 file in /boot/grub. Is it ok to boot from an efs3 partition?
How can I debug this? NOTHING is written to the screen, no splash, no messages, no nada.
