Description of problem:
We have a PII (Klamath) 266MHz machine with a PD440FX motherboard. Using RedHat
7.2 (2.4.9-31 kernel) it works fine. Indeed, using my standard build mozilla
lots of times test it is very stable. On upgrading to RedHat 7.3 (2.4.18-4
kernel) it usually crashes in the install (hard disk light stays on, network
stack is pingable, but can't log in), or later when untarring a large file on
the hard disk. This hard disk is a Quantum Fireball ST6.4A.

RedHat 7.2 doesn't switch on DMA automatically, but 7.3 does. Switching on DMA
on 7.2 gives messages like:

May 29 10:26:05 xpc6 kernel: hda: timeout waiting for DMA
May 29 10:26:06 xpc6 kernel: ide_dmaproc: chipset supported ide_dma_timeout func
only: 14
May 29 10:26:06 xpc6 kernel: blk: queue c0352660, I/O limit 4095Mb (mask 0xffffffff)
May 29 10:26:06 xpc6 kernel: hda: status error: status=0x58 { DriveReady
SeekComplete DataRequest }
May 29 10:26:06 xpc6 kernel: hda: drive not ready for command

However the machine doesn't crash. Should 7.3 be disabling the DMA for this
setup. Why does this crash on 7.3 and not on 7.2?

How reproducible:
Always

Steps to Reproduce:
1. Install redhat 7.3
2. Untar mozilla tarball
3. Crashes

Comment 1 Jeremy Sanders 2002-05-30 11:36:30 UTC
More information: we have an identical system (same type of hard disk and
motherboard). The install fails in exactly the same way. This looks like the
kernel doesn't support this motherboard (or disk).


Comment 2 Arjan van de Ven 2002-06-05 10:02:40 UTC
Installing with ide=nodma on the syslinux prompt will work
Now to find out why the kernel decides to enable dma...

Comment 3 Jeremy Sanders 2002-06-05 12:02:27 UTC
Confirmed. Using ide=nodma the system works fine (and installs).

Comment 4 Bugzilla owner 2004-09-30 15:39:38 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
