>Originator:     Dennis den Brok
>Release:        Applies to kernels at least up to 2.1_RC2.
>Organization:
-
>Environment:
NetBSD 2.1_RC2
>Description:
Kernel messages include: 

<missing stuff>, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)
wd0(siside0:0:0): using PIO mode 4, Ultra-DMA mode 2 (Ultra/33) (using DMA data transfers)

This indeed has impact on the drive's speed.
>How-To-Repeat:
Boot a NetBSD kernel up to at least version 2.1_RC2 on a system as described.
>Fix:
I asked for a solution to this problem about three years ago (time's going by so fast) and was quickly supplied with a working patch from Manuel Bouyer which apparently never made it into CVS repository. Unfortunately, I don't have it anymore (and most probably it wouldn't be recent enough, anyway), maybe Manuel still has it or is able to reproduce it without much effort and can commit it to CVS?

 Note: also see

    http://mail-index.netbsd.org/tech-kern/2008/04/01/msg000859.html

 and descendents, the gist of which is that the submitter no longer has
 the hardware to test but there's no particular reason to suppose the
 problem is fixed.

 Also there's a note

  > I think that this behavior might have been specific to this
  > particular board by Elitegroup, which belonged to their
  > battery-less "DeskNote" laptops and thus aren't probably in too
  > widespread use.

 which is of interest for any future testing attempts.
