I have several Open Compute systems (20+) that I am installing via the serial console via IPMI. On CentOS 6.3 and 6.4 if I add "serial console=ttyS1,57600n8" to the kernel parameters the install works fine and I can see the progress from the SoL port however after the system reboots all I get is a blinking cursor. If I boot from a CD and go into rescue mode I can see that it is installed properly, grub is there in the MBR and everything is fine but the system will not boot from the HDD. After some trial an error I found that commenting out the serial line in the grub.cfg I could reboot the system.<br />
<br />
#serial --unit=1 --speed=57600<br />
<br />
To fix this I added a simple sed command to the post section of the kickstart and all is good.<br />
sed -i "s/\(.*\)\(speed\)/#\1\2/g" /boot/grub/grub.conf
