The card has mailbox space for 192 concurrent commands, your device configuration will allow at most ~68 concurrent commands, yet we ran into a mailbox that was left in the 'busy' state which should never happen. Leonard Zubkoff's BusLogic page also lists your firmware as problematic. Take a look at: http://www.dandelion.com/Linux/BusLogic.html for more information. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
