Bug ID: 255012
Summary: iwn driver kernel panic
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: wireless
Assignee: wirel...@freebsd.org
Reporter: nathanielbarragan1...@gmail.com
The iwn driver, after a few hours of use, will kernel panic with a page fault.
It would seem that it occurs in iwn_rx_compressed_ba(). This is reproducable.
Steps to reproduce:
1. Connect to an AP (in my case it's using wpa_supplicant using WPA2 PSK)
2. Allow traffic to flow in and out of the interface (In this case, you can
just ping an address, and to speed up the process, put a wait time of 0.1 is
what I do to reproduce, but this happens during normal usage as well)
3. Wait for kernel panic.
Attached is a screenshot of the backtrace (please excuse the quality, I only
had a phone camera available), and am available to help as needed, although
response may take anywhere from instant to a few days. No longer than 3 days
usually.
