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):
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.
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.
See patch for ide-dma and ali15x3 in 2.4.20-pre2-ac4
Does ide0=nodma also fix the hang on your devices btw ?
Actually, none of the ide0 parameters seems to work (noprobe, nodma, notune)
BTW, this issue is also present in the latest 8.0 (NULL) beta that is out.
