Okay, I'll change the quirk entry to be something like this:


==== //depot/cam/sys/cam/cam_xpt.c#168 - /usr/home/ken/perforce/cam/sys/cam/cam_xpt.c ====
*** /tmp/tmp.2966.0	Wed Oct 14 16:43:41 1998
--- /usr/home/ken/perforce/cam/sys/cam/cam_xpt.c	Wed Oct 14 16:43:25 1998
***************
*** 264,269 ****

  		{ T_DIRECT, SIP_MEDIA_FIXED, "MICROP", "3391*", "x43h" },
  		/*quirks*/0, /*mintags*/0, /*maxtags*/0
  	},
+ 	{
+ 		/*
+ 		 * Broken tagged queuing drive
+ 		 * Reported by: Bret Ford <bford@uop.cs.uop.edu>
+ 		 *         and: Martin Renters <martin@tdc.on.ca>
+ 		 */
+ 		{ T_DIRECT, SIP_MEDIA_FIXED, "SEAGATE", "ST410800*", "71*" },
+ 		/*quirks*/0, /*mintags*/0, /*maxtags*/0
+ 	},
          {
  		/* Broken tagged queuing drive */
                  { T_DIRECT, SIP_MEDIA_REMOVABLE, "iomega", "jaz*", "*" },


That should disable tagged queueing for the drives that have been reported
as broken, but keep it enabled for the ones that have been reported to work.
