Description of problem:
System will boot smp clear through to the login prompt, no errors.

But as SOON as the kernel inits at the start of the boot process, *all IO locks
up*.  No keyboard, no mouse, no network, nothing.

So once the system has finished booting, it's completely unusable : it sits
there blinking a cursor, and is totally inaccesible via keyboard, mouse, or network.

This happens regardless of runlevel (single, multiuser, X).

Verified on a stock FC4T3 install, and with all yum updates installed, and on every
2.6.11 FC4 smp kernel available right up to the new 1363 one.

System was installed as "server", with all defaults taken during install.

Logs not only show no errors, but do not log the fact that the system booted
smp, period.  It's like syslog never even ran.

Board is a Intel SE7501CW2, with two 1.8ghz Xeons, 512mb memory.

There are NO io cards installed, and the system is stock off the FC4T3 isos.

I've tried running all yum updates; no help ... I've tried every FC4 smp kernel
from FC4_1267 to the current 1363, all have the same exact result.

It makes no difference if I'm running the stock install off the ISOs, or have
run yum update to bring to current.

All of the above kernels boot perfectly in *non* smp.  It's just smp kernels --
any smp --that flat-out fail.

Knoppix 3.82 (running a 2.6.11 kernel) boots flawleslly into smp.
