Based on the photograph, it seems like your framebuffer base address
is 0x7a_1000_0000 which is above the 32-bit boundary.  When you enable
"prom_debug" and "kbm_debug", there is some early boot code which
can't use a 64-bit address to write to the display.  This ultimately
causes the writes to go off into space, and may collide with other
memory that upsets the boot process.

This is described in a ticket I'm working on at the moment for another
system that has this problem:

    17548 early boot framebuffer reach exceeds grasp
        https://www.illumos.org/issues/17548
        https://code.illumos.org/c/illumos-gate/+/4350

Should hopefully be finished soon!


Cheers.
