if you have an ide cdrom, could you try booting without?

i spend a few hrs the other day poking around at a similar
problem.  my atom board will not reboot via
	echo reboot /386/9pccpu>/dev/reboot
if i have an ide cdrom attached.  it hangs in approximately
the same place.  (though it's hard telling, since there are many
things that happen between the memory line and version ... time.)

here's what i know so far
1.  the typical warning about a spurious ipi (inter-processor
interrupt) on reboot is missing.
	cpu0: lapicerror: 0x00000000
i don't know what that means yet.
2.  compiling sdata out of the kernel results in proper booting.
rebooting after the ide interface has been touched  is fatal, even
if ide is compiled out of the reboot kernel.
3.  the boot process is started but the machine will lock solid
on the first sleep.  (typically the wait(2) for ip/ipconfig to run.)
