Well, I somehow managed to make one adapter unresponsive.
It was either by jumpering the SE & RSV.4 jumpers at the same time,
or jumpering RSV.1 .
the behavior afterwards is, the device no longer is detected, yet also does not cause the scsi host to timeout on the detection,ergo it's stuck.
When id.3 is jumpered (device id 8 set), the host still does not find a device, yet the bus detection proceeds without problem.
I'm going to take the eeprom off and verify the contents just to be certain it's not somehow a firmware fault.
