As I pointed out in my PR, "make -j4 buildworld" is more than sufficient
to demonstrate the problem.
This is why I don't understand why it has been ignored - it is easily
reproducable using stock Adaptec SATA controllers, standard SATA drives,
and a gmirror RAID 1 configuration.
This is pretty pedestrian stuff here Robert.... Two disks on one adapter,
on a PCI bus.....
I'll pull over 6.0-BETA1, rebuild the array (that is the time-consuming
part of this test - takes 6-8 hours for the rebuild to run) and see if it
fails during a buildworld.
