Hmm, I am running r360723 (GENERIC) on my RPi4 and it shows "hw.physmem:
4127662080".

I can confirm that USB (and Wifi) is not working:

usb_nop_xceiv0: <USB NOP PHY> on ofwbus0
simplebus0: <usb at 7e980000> mem 0x7e980000-0x7e98ffff,0x7e00b200-0x7e00b3ff irq 44,45 disabled compat brcm,bcm2708-usb (no driver attached)
usb_needs_explore_all: no devclass

Powerd reports "no cpufreq(4) support". No idea if it runs at full
speed or not.

I have two issues with the ethernet adapter (genet0):

1. Apparently, my RPi4 is sending icmp replies to the wrong destination!?

Ping from laptop to RPi4:

% ping -c 1 192.168.0.9
PING 192.168.0.9 (192.168.0.9) 56(84) bytes of data.

--- 192.168.0.9 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms

tcpdump on laptop:

23:20:22.244458 IP 192.168.0.2 > 192.168.0.9: ICMP echo request, id 14, seq 1, length 64
23:20:22.244651 IP 192.168.0.9 > 192.168.255.191: ICMP echo reply, id 14, seq 1, length 64

tcpdump on RPi4:

23:20:22.247490 IP 192.168.0.2 > 192.168.0.9: ICMP echo request, id 14, seq 1, length 64
23:20:22.247562 IP 192.168.0.9 > 192.168.0.2: ICMP echo reply, id 14, seq 1, length 64

Ping from RPi4 is OK.

2. IPv6 (accept_rtadv) is not working.

And the RPi does not reboot.
