I can't quote exact uname -a because NetBSD is not on the machine anymore.
It was a Generic-Laptop stock kernel, i386 NetBSD 3.0.

I have installed NetBSD 3.0 (GENERIC_LAPTOP stock kernel) on a DELL
Latitude XPi P133ST laptop. 
DELL specifications are here:

I own an external pcmcia/scsi CD-ROM reader (PANASONIC KXL-D740).
PANASONIC specifications are here:
Under the CD-ROM reader, on its back, there are four micro-switches (DIP):
  SCSI ID 1 (On/Off): On
  SCSI ID 2 (On/Off): Off
  SCSI ID 3 (On/Off): On
  Terminator (On/Off): On
This CD-ROM reader was functionning properly under Windows 98 and Debian
Sarge whith these settings.

When I plug the CD-ROM reader in the PCMCIA slot1 (an ethernet card
being plugged in slot0), it crashes and ddb prompt appears: 

  -bash-3.1# 1esp0 at pcmcia1 function 0: <KME, KXLC002, 00>
  pcic0: port 0x410-0x41f
  pcmcia1: card irq 11
  uvm_fault(0xc0657e60, 0, 0, 2) -> 0xe
  kernel: page fault trap, code 0
  Stopped in pid 5.1 (pcic0,0,1) at     netbsd:ncr53c9x_init+0x4c:    movl

result of bt:

Just plug in the Panasonic pcmcia card in the laptop.
