"Hello, I've just upgraded my OS to Windows 2000..."
"Yes...?"
"Well, my computer doesn't work now."
"Yes, you just said that a second ago."
>Environment:
System: NetBSD starjumper 1.5V NetBSD 1.5V (STARJUMPER) #3: Sun May 20 15:05:32 PDT 2001 greywolf@starjumper:/export/src/sys/arch/i386/compile/STARJUMPER i386

>Description:
	Once every 24 hours or so, after some instances of
	"fxp0: WARNING: SCB timed out!"
	and
	"fxp0: device timeout"
	the machine locks solid, to the point that ddb does not
	even kick in.  There is no panic, no reboot, no nothing.
>How-To-Repeat:
Here's my boot log.  Feel free to ask for more info; I'll give what I can.
