This occurs every time the wifi connection is configured, up and being acti= vely used, but the precise timing varies. It appears to be related to the overall volume of traffic. The panic sometimes occurs within minutes of cold boot, sometimes up to a quarter of an hour later. This issue appears to be specific to FreeBSD 13.3. It does not arise on the same machine running a fresh install of FreeBSD 13.2 (which runs regularly = for at least 8h under heavy wifi load with no issues). Nor does the difference appear to be due to configuration issues. Under both FreeBSD 13.2 and 13.3,= I use a custom kernel where the only change from GENERIC is to enable options= for BWN_DEBUG and BWN_GPL_PHY. Both machines have correct firmware installed by building the port net/bwn-firmware-kmod with no special options. --=20 You are receiving this mail because: You are the assignee for the bug.=
