Description David C. Shaw 2003-10-25 13:55:08 UTC
Description of problem:

DMA not available for the stock IBM hard drive on DEC HiNote Ultra 2000.  It IS
available under e.g. Windows NT.  Have to boot using ide=nodma or else enter
/sbin/hdparm -d0

An early symptom, maybe, is a message saying "BIOS not fully configured" and
"channel 00.08.00 unavailable" during boot.  I am running the latest DEC release
of the BIOS - v.1.07

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

Linux v.9

How reproducible:

During installation - without entering "linux ide=nodma" installation is
pathologically slow.

Once installed - setting "/sbin/hdparm -d1" hangs the machine.

Steps to Reproduce:
1. Either - try installing from CD with default procedure,
2. Or, try "/sbin/hdparm -d1"
Actual results:

Pathologically slow performance

Expected results:

Faster performance than DMA disabled!

Additional info:

Latest BIOS from DEC (i.e. HP!) installed and hardware checked.  DMA works under
Windows NT.  "hdparm -I" shows that even udma2 should be available for this disk.

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

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/
