Missing XL0 and USB printer after upgrade

[bcsfd204 at twcny.rr.com]

I upgraded two systems over the weekend (2/6-7/04).  I came up from a 5.1-CURRENT level from around October, 2003.  Both are Tyan dual AMD processor systems with built in XL class ethernet cardss.  I reviewed UPDATING and I believe I followed the instructions for the multi-terabyte changes.  The desktop kernel and world went without much of a problem (except nautilus keeps crashing on a segment fault.  I think I have to upgrade Gnome but I was going to do that later.)

I then went to upgrade the server.  When I finished booting the machine, XL0 and my USB attached printer were not recognized (present).

IFCONFIG does not show XL0 and ls /dev does not show my USB printer.

I played with the kernel config (the two machines are almost identical (currently defined but disabled SCSI controller in the server machine))  I also tried SCHED_ULE and SCHED_4BSD and it did not seem to change anything.

What I am noticing for the printer is, I get most of the probe messages but then I start getting the messages about the filesystems being clean and root being mounted.  During this portion of the boot, I get messages about the USB hardware being probed.

It's almost like the hardware probing is not done yet before the kernel startes to mount the filesystems and begin initialization.  (If I mangled the process here I'm sorry.  I'm trying to describe what the external symptoms look like.)

When I review DMESG output, there is nothing present for the XL-class ethernet interfaces.  I also tried adding a VX-class card I had in the closet but this is not detected either.

At the moment, I'm less concerned about the printer.  I'm going nowhere with this server box if I cannot get it back on the wire.

Any thoughts?
Thanks...
