With march 12 and 13 sources I'm getting the following on boot with
new kernel.  march 11 kernel is fine...
bootup messages:
	using 123 buffers containing 503808 bytes of memory
	biomask 0 ttymask 0 netmask 0
	panic: cannnot mount root
	stopped at _Debugger+0+4: leave
and not that I know what the heck this means :-) I give db the trace cmd.

_panic(f8106a65,176f9c,181000,181000,9) at _panic+0x54
_main(181000,0,0,0,0) at _main+0x2b4

I've recompiled and installed config.  I'm not configuring anything
differently from march 11, i.e. wdc0 or fdc0 configured but not
But I suspect I must be missing something.  

This is dmesg from working working kernel:
