I compiled a custom kernel with the options you specified. When I do a
normal boot (xhci mode) using the custom kernel, instead of a hang I get
a panic. The last lines on the screen before the panic instructions are:
scscibus3 at softraid0: 256 targets
panic: root device (4c16713a536188bf) not found
stopped at Debugger+0x9: leave
The keyboard does not respond after the panic.
Booting the custom kernel after putting the laptop into ehci mode I'm
able to boot successfully and get a dmesg, though perhaps not the one
you need, since its no longer in xhci mode. :( Here it is:
