If you are getting controller resets during driver load, you must not be getting interrupts or firmware is not responding to the inquiry roll-call. Make sure you have the latest firmware. The code at the end of megasas_adp_reset_gen2() just looks for DIAG_RESET_ADAPTER flag to clear on the host diag register when issuing a controller reset... that should happen almost immediately unless there is a hardware or firmware issue. Are you sure your 'new' motherboard is actually good ? Can you move your megaraid 9240-8i into a 'known working' system and re-test ? -Adam -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
