I have this nice new 2gig drive which is right now on my second channel and locks up my freebsd system any time i try to access it... My feeble attempts at trying to serialize requests in the kernel only resulted in the processes freezing that try to access the second disk, a slight improvement, i guess :-) but, does anyone have a solution to this??? I'd rather not get another ide controller just for this drive... -- Jason Garman http://www.nesc.k12.ar.us/~garman/ Student, Eleanor Roosevelt High School garman@phs.k12.ar.us
