 This will be the exact same reason I'm unable to boot -current on my machine
 then.  I expect to obtain a serial cable in the next few days and will be able
 to supply the output of boot verbose at that point.
 
 Mike, if you're in a position to do this any earlier then if you could do so
 that would be great.

Soren, is there much you can do with this at the moment ? 
I'll have a serial cable by the weekend hopefully, but if you can see why 
this might be occurring in the meantime that would be fine. 

Thanks,

 I'm not properly set-up to do a full remote gdb debug.  I have a feeling
 there is nothing too tricky about this bug.  The TX2 board contains an
 ISA_MADDR_0 configuration and the acpi routine isn't prepared to handle t=
 his.
 Either acpi_read_ivar needs an additional case to handle this or we need =
 to
 re-route through an ISA handler function.  I imagine an ACPI person knows
 what to do.
 
 For the time being, I'm working around the problem by disabling ACPI at
 boot (hint.acpi.0.disabled=3D"1" in my /boot/device.hints file).

State-Changed-Why:  
This is hacked around for now.  Real fixes for the problem are needed 
but are unrelated to the TX2.
