Description Rajeev Pillai 2020-09-28 10:24:07 UTC
Machine: ASUS X202E laptop

After a warm reboot (Ctrl-Alt-Del) from Ubuntu Linux 19.04 into
FreeBSD/amd64 12.1-RELEASE-p10, networking stops working. The
kernel displays this message:

ubt0 on uhub4
ubt0: <Atheros Communications Bluetooth USB Host Controller, class 224/1, rev 1.10/0.02, addr 3> on usbus1
WARNING: attempt to domain_add(bluetooth) after domainfinalize()
WARNING: attempt to domain_add(netgraph) after domainfinalize()

ping to any host on the network fails with a "host is down" error.

There is no error message like the above, and no networking problem, after a cold
reboot (shutdown -P now, then switch on) from Linux.

I've noticed the same error message and the same networking not working issue
on another laptop.

Incidentally, warm rebooting from FreeBSD 12.1-RELEASE-p10 (on laptop) into FreeBSD
12.2-BETA3 (on USB-stick) and doing a dmesg, shows the kernel logs from the old
kernel as well as the new one.
