With boot -v the kernel gets as far as
isa_probe_children: Probing PnP Devices
I've compiled and run a kernel with the DDB option.
On the third attempt I got lucky and managed to get into do a trace. I
didn't bother to write down the enty points etc
Debugger()
scgetc
atkbd_int
atkbd_isa_int
Xresume1()
----Interput, esp= etc
doreti_next
mi_startup
begin ()
I ran continue a few times in the debugger and the kernel seemed to be
looping around doreti_next with the occational call to vec1.
Any ideas on where to go from here.

If you could compile up a custom kernel with the following options:
options DDB
And then when it hangs try doing a CTL-ALT-ESC. If you get the ddb>
prompt, do a 'trace'.
