Log is identical to the one I posted earlier (modulo the build timestamps),
except this part:

 eeprom0: <EEPROM/clock> addr 0x1400002000-0x1400003fff on ebus0
-eeprom0: cannot allocate resources
-device_attach: eeprom0 attach returned 6
+eeprom0: model mk48t59
 ebus0: <fdthree> addr 0 (no driver attached)
-ebus0: <su> addr 0x14000003f8-0x14000003ff irq 43 (no driver attached)
+uart0: <16550 or compatible> addr 0x14000003f8-0x14000003ff irq 43 on ebus0
+uart0: console (9600,n,8,1)
 ebus0: <kb_ps2> addr 0x1400000060-0x1400000067 (no driver attached)

Kernel still hangs at the same place.

Yes, it was committed as part of r287726.  Because commit log did not have
reference to D2791, it had to be closed/abandoned by hand.
