Setting ncr53c9x_debug to 0x3ff (covering all flags as far as I could read)
gives the following boot messages:
esp0 at obio0 (quick): address 0x8b0000: NCR53C96, 16MHz, SCSI ID 7
[NCR_INIT(1)] <cmd:0x2><cmd:0x0><cmd:0x3>scsibus0 at esp0: 8 targets, 8 luns per target
several lines about zsc0 and zstty0 and 1
nubus0 at mainbus0
fpu0 at mainbus0 (mc68040)
scsibus0: waiting for 2 seconds for devices to settle...
[ncr53c9x_scsi_cmd] [0x0, 6]->0
and that's it -- here the machine hangs still.
Pressing the debug button and doing a t command to ddb gives
panic: lockmgr: no context
