Hi, We have a 2.0.36 redhat 5.1 machine running with SMP and it is crashing regularly under heavy load. There is something in the dump on screen about 'Bus master' problems or something .. I know there was a fix for this driver under SMP posted before, but I cant find it. Anyone able to elucidate me? :) Nathan Ollerenshaw <chrome@grid9.net> Grid9 Technical Manager Mirage Networking Limited
