UPDATE :
I was able to get past this problem. I had to run the install with 'irqpoll' option. The install appears to finish correctly and reboots. Now I'm having trouble getting the system to boot, even using irqpoll as a kernel option.

Hello,
I'm trying to install RHEL 5.4 to an Intel Core2Duo architecture, 6300ESB and e7520 MCH. The install keeps getting hung. It depends on which kernel options I use but usually it gets hung after asking for the RH 'installation number', on the blue screen. I'm always running in text mode. I've tried various combinations of the following kernel options :
noapic acpi=off all-generic-ide nousb ide=nodma

The furthest I've been able to get is installing with :
all-generic-ide nousb noapic

and it seems to hang after 'running /sbin/loader'

Any suggestions?

I've had Ubuntu running on this same hardware (booting from CD) and I'm able to boot a cloned drive of RHEL4 (from a different single core system).

Regards,
Brent

What's the difference between the cloned and the installed system?
Kernel type? Architecture? Settings?
If I have trouble installing, sometimes I will do a bare bones setup and build everything from the base.
