[rhelv6-list] Dell servers stopping at GRUB if no manual input

[Darren Patterson]

This sounds like the ancient serial console timeout issue that was mitigated by changing the terminal line to be:
terminal -timeout=5 serial console

Specifically, remove one hyphen before timeout.  Cobbler has setup all my systems like this at build time like this since RHEL3.  If this bug and subsequent work-around is still bothering people using serial console, it wouldn't surprise me.

Thanks,

They just appear to stop at some point and are non-responsive via any method (connecting to the DRAC/serial console, or plugging in a keyboard and mouse) until rebooted.
