Description of Problem: When trying to install RedHat 7.1 on my system I 
boot from the RedHat 7.1 CD. I choose expert mode to be able to install 
the kernel module for the FastTrak controller 
(ftp.promise.com/Controllers/IDE/Linux/).  When the kernel starts booting 
and probing my PCI cards it detects the FastTrack controller as a PDC20262 
controller (without RAID capability).  As soon as it then starts probing 
the hd's attached to the controller there are two cases:
1 there is a Raid build on the disks: the system will hang and a cold 
reboot is needed to be able to access the disks again
2 there is no raid build on the disks, the kernel will continue booting 
but I am not able to choose from a list of controllers after I have 
inserted the driver disk.  The program does an automatic search (rescan?) 
of the pci bus but does not load the module.  In a further step in the 
installation (fdisk) it reports bad disks and wants to format them.

How Reproducible: I tried to remove all other pci cards, no difference.  I 
also tried different pci slots, no difference either.

Steps to Reproduce:
1. put a promise FastTrak controller in your system
2. attach a disk to the contoller (or two to build a raid)
3. boot from the RedHat 7.1 installation cd

Actual Results:
installation on these disks is not possible
system hang when raid is build
no partitions detected when no raid is build

Expected Results:
a nice and clean install of this new RedHat release
Comment 1 Arjan van de Ven 2001-05-20 12:33:13 EDT
The Promise binary-only, propriatry, module is NOT supported. Please report this
bug to Promise, not to us. There is nothing we can do to help/fix this, as
Promise refuses to cooperate and/or release sourcecode.
(The module also eats your disks, but that it not my problem). 

Having said that: I'm working on an opensource version that does support the
Promise RAID format.
