7.0-CURRENT Hang

I'm experiencing the following hang on my -CURRENT testbed (which also 
serves as a 4.11, 5.4, and 6.0 testbed). Only under 7.0-CURRENT does it 
hang during boot using a stock out of the box GENERIC kernel. The machine 
is an old P120. Any ideas?

OK include /boot/cwtest/foobar
|

cwtest.foobar loader file selected
unload complete
currdev set to disk2s1a:
/boot/kernel/kernel text=0x4e15c4 data=0x84900+0xa026c 
syms=[0x4+0x67ea0+0x4+0x7f4ff]
new kernel has been loaded

OK boot -s
GDB: no debug ports present

WARNING: WITNESS option enabled, expect reduced performance.

At this point I need to reset the machine.
