Yeh I do have a mix of 150 and 300 drives. The problem is with the 300 
drive though. I do remember reading somewhere of a bug in the NCQ part 
of the kernel and also an issue with Promise boards in particular. That 
was some time ago though and I thought that it was already fixed. Based 
upon what you are saying it sounds like it hasn't. I did notice that the 
problem seemed to have started at the time I added the 4 port card 
replacing a 2 port 150 card.
