Obviously I can only comment on my own hardware but the machine has been used 
constantly since Thu Jul 12, its now Jul 30 and I havent had a single IDE 
related problem. 

As a hobby, i use the machine for DigitalVideo, and regularly grab 20-30GB 
from my capture card, then process it, which means the IDE bus gets a lot of 
use and seems to be an ideal situation for the data trashing problems to rear 
their ugly heads (no pun intended) but, as i said, I haven't seen any here.

DRAM Prefetch makes my sound usuable, as the VIA fixups for the SB cards do 
not work here, and for (at least) two other people who i have had email 
correspondancy with.
