Kernel messages look like if controller or device stuck, unable to complete some command and can't recover from that condition even after device hard reset. I don't see what driver can do about it, except being more aggressive in dropping faulty device after several consecutive timeouts. If that is not a wanted way out, start from updating card BIOS and devices firmware. -- Alexander Motin _______________________________________________ freebsd-hardware@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "freebsd-hardware-unsubscr...@freebsd.org"
