Log message:
Pull in patch from current:
Fix (krw):
This fixes a problem that caused DMA errors from shortly before
2.7 through the released 2.8.

As NetBSD describes the problem:

DMA failure still arise when AdvanSys U[2]W host adapters
are used in conjunction with Intel 82443BX Host
Bridge/Controller (rev. 0x03).

With a correct sg_cnt, scatter/gather lists with >1 element
no longer reference random(?) memory. Now the mystery
is why this didn't cause more problems on other chipsets.

Installs of 2.7 and 2.8 to a drive on an adw bus now work even
if the motherboard uses the 82443BX.

So many problems from one character ...
