AP seems to refer to the CPU, the "application processor"
See for comparison this dmesg output:
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
FreeBSD/SMP: 1 package(s) x 2 core(s)
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 1
Here we see BSP ("bootstrap processor") and AP.
PHY seems to refer to physical characteristics of interfaces.
Again from "dmesg | grep PHY":
nsphy0: <DP83840 10/100 media interface> PHY 24 on miibus0
ukphy0: <Generic IEEE 802.3u media interface> PHY 1 on miibus1
You often see comparable output related to NICs. For example,
if you search "man rl" for the string "PHY", there are refernces
to the physical chipset (physical layer, as opposite to the MAC,
the media-independent layer). It's a reference to the OSI layer 1.
So in your case, the error refers a panic of the application
processor, which is the 1st physical processor.
I hope my guesses are correct. :-)
