This is a Toshiba Tecra 500CDT laptop (i386) with 3COM 589 pcmcia ethernet card
and Adaptec APA-1460 SCSI Host Adapter with an IBM DCAS-34330 attached
to it. The dmesg normally looks like:

>Description:
	
When booting a current kernel (build from src supped at 22.11.1998)
on my laptop with just the Adaptec pcmcia card inserted, but no
disk attached to it, it works like normal.

But at home, where I have a IBM DCAS-34330 4GB scsi disk attached,
the kernel hangs after telling the biomask - the scsi drive LED
remains on:

[...]
	[ did not write down everything before that ]

aic0 at pcmcia1 function 0 port 0x340-0x35f: Adaptec APA-1460/B SCSI Host Adapter
scsibus0 at aic0: 8 targets
pcmcia1: card irq 9

	[ Note that the normal bootup shows this "pcmcia1: card irq 9"
	  after the disk probe ]

sd0: 4134MB, 8205 cyl, 6 head, 171 sec, 512 bytes/sect x 8467200 sectors
apm0 at mainbus0: Power Management spec V1.1
apm0: battery life expectancy: 96%
apm0: A/C state: on
apm0: battery charge state: high charging

biomask c040 netmask c040 ttymask d0ca

	[ Note that this biomask differs from normal boot too! Normaly its
	  biomask c240 netmask c240 ttymask d2ca ]

stray interrupt 9
pcmcia1: card irq9

And now the machine just hangs - the LED from the disk is still on.
If I try a reboot via CTRL-ALT-DEL the LED keeps being on and the
bootup hangs at the same part, but this time constanly printing:

probe(aic0:0:0): timed out
probe(aic0:0:0): timed out AGAIN

A kernel build from src supped 17.11.1998 works ok, so something
in between must have broke this.

>How-To-Repeat:
	

Boot a current kernel on a Toshiba Tecra 500CDT laptop (i386) with
an Adaptec APA-1460 PCMCIA SCSI Host Adapter and a scsi disk
attached and watch it hanging.

Wish I would know, sorry :-(
