Does the NCR driver still support the "poll" mode ?? if so that might be why it works, the NCR driver doesn't use the intr after it timed out sufficently many times, this tricked me once under the old SCSI system... The ata driver should check for getting a "real" interrupt though... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
