Description of problem:
The default install of RH7.2 on a Compaq Armada E500 notebook (model number AE5 
P3900T4X20DC12N2T) does not work with the machine's IDE disk controller.  This 
results in file system corruption and data loss.  This issue can be fixed by 
passing the ide=nodma option to the kernel at boot time.

filesystem is failing.

Expected Results:  None of the above.  The installer should detect the IDE 
controller and configure the boot loader to pass the ide=nodma option to the 

Additional info:

Passing ide=nodma to the kernel at boot time fixes the problem.
