Description of problem:
Drive access to Fujitsu EA drives (model MHR2040AT) through a ALi1535
SouthBridge (ALi15x3 IDE controller) locks up the controller and installation or
boot fails.  The kernel checks the drive compatibility and determines in can
perform 48-bit sector addressing and in ide-dma.c tries to access the drive with
a 48-bit sector address, which the ALi cannot handle.

This problem was reported to Andre Hedrick who added a patch and is incorporated
in 2.4.20-pre2-ac4.  We would like RH to issue an errata for this.

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


How reproducible:
Always

Steps to Reproduce:
1.Try to either install RH 7.3 on a system with an ALi1535 SouthBridge and the
noted Fujitsu (or any ATA-6 compliant) drive.
2. Or take a RH 7.3 install and try to boot it on the described system and it
hangs at the partition check.
3.
	

Actual Results:  Either hangs at install or hangs at boot on the partition check.

Expected Results:  It should have correctly detected the drives and comprehended
that the controller can only perform 28-bit sector addressing.
