I have been running CAM for the last month or so, and it is a LOT more stable than the previous code, but there is a problem with SCB's. If I stress the disks too much, I start getting the message "Timedout SCB handled by another timeout" (from aic7xxx.c). This message repeats itself ad nauseam at about 5-10-sec intervals, and the machine is unuseable. A reset is necessary to get it going again. Any clues? Could this be a race condition in the SMP case?
