Bug ID: 249952
Summary: Networking stops working after warm reboot from Ubuntu
Linux 19.04 on FreeBSD/amd64 12.1-RELEASE-p10
Product: Base System
Version: 12.1-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
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.
