Description James Riggs 2001-07-23 12:57:14 EDT
Description of Problem:

When installing RedHat 7.1 or Fairfax Beta1 or Beta2 onto an IBM
IntelliStation 6849 using CDRom.  The Install locks unless ide=nodma is
passes to the kernel.

"cat /proc/ide/hdc/model"  == CRD-8480C
Comment 1 Arjan van de Ven 2001-07-23 13:00:33 EDT
Added to the NODMA list, thanks for the report!
Comment 2 James Riggs 2001-09-05 13:49:20 EDT
Tested again with release canadate 2.  Still have to add ide=nodma as boot
option to access CD Rom.  If dma is not turned off Accessing the CDRom will lock
the machine.
Comment 3 James Riggs 2001-09-12 10:22:42 EDT
Tested again with Enigma.  Able to boot install without entering ide=nodma.
