Bug ID: 298417
Summary: Destroying rtw89(4) freezes the system with the
INVARIANTS kernel
Product: Base System
Version: 15.1-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: wireless
Assignee: wireless@FreeBSD.org
Reporter: temcbun@gmail.com
May be related to bug #296185 (the same symptoms). My specs could be obtained
from that bug. I'm still running stable/15 (synced and compiled a couple of
minutes before reporting this bug).
The system is freezed when the rtw89(4) interface is destroyed using
ifconfig(8) and the kernel is compiled with the INVARIANTS option (the freeze
does not happen without INVARIANTS).
Steps to reproduce:
---------------------
$ ifconfig wlan create wlandev rtw890
wlan0
$ ifconfig wlan0 destroy
** The system freezes **
---------------------
