Regardless how high/low the load is, the machines will eventually lock up when using adaptec SCSI controllers. No idea whether i= t is the driver or the hardware, but replacing the controller with the same= model didn't fix it while exchanging it against another brand always fixe= d it. Buggy hardware, buggy driver, I don't care. If it doesn't work out of the= box, another manufacturer gets the money next time. Carl-Daniel
