Description of problem:
i have my system on a WD 1200JB drive hanging off of a promise UDMA 100 TX2 pci
card as /dev/hde.  it works flawlessly with redhat 7.3 and the 2.4.18-5 kernel
in udma mode 5 (UDMA100) and has been working flawlessly in that mode for over
two months.  when booting the kernel for the (null) installer, it complains when
probing the drive at bootup.  it gives several 'hde: lost interrupt' errors and
then several more verbose DMA errors when the kernel gives up and resets the
promise interface. i've never gotten the installer past this point and even if
it could get past it, i wouldn't trust such flaky support for my main IDE
interface. 

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. insert promise UDMA100 TX2 card into computer
2. attach drive to promise controller
3. boot (null) installer
4. installer will run until it probes the drives on the promise controller at
which point it will fail
	

Actual Results:  install kernel would loop trying to get the drive on the
promise configured.  i would let it go a few minutes before giving up. 

Expected Results:  it should have recognized and configured the drive/controller
normally like the redhat 7.3 kernel does. 

Additional info:

i have a second drive on an on-board IDE controller that was detected and
configured properly.  the on-board controller is also UDMA100, but uses an SiS
5513 chipset.  the motherboard is an MSI 645 ultra with a pentium 4 1.6A cpu.
