iwlwifi caused a kernel panic

xmine64 · 2025-11-20T13:06:32+0000

Hey, I wanted to report that sometimes my system freezes and reboots when I connect to an access point.
I don't know if it's random or there's a trigger but it happened 3 times in a row, and every time I was trying to connect to my iPhone's hotspot and after failing I tried to reconnect to home's router.
It's an Intel 2022 Legion 5 with AX211 WiFi card, running FreeBSD 15.0-RC2.

Code:

iwlwifi0@pci0:0:20:3:    class=0x028000 rev=0x01 hdr=0x00 vendor=0x8086 device=0x51f0 subvendor=0x8086 subdevice=0x0094
    vendor     = 'Intel Corporation'
    device     = 'Alder Lake-P PCH CNVi WiFi'
    class      = network

This is what I could find related in /var/log/messages:

Code:

Report on freebsd-wireless@FreeBSD.org mailing list. The developer of the iwlwifi driver (Bjoern A. Zeeb.) is asking to test, and to report issues on that list.

Please test new drivers in main (iwlwifi, rtw88, rtw89)

This card should be supported by iwx driver from OpenBSD which is added in 15. i have ax210 and iwx is great more stable than iwlwifi. this does not mean the problem should not reported quite the opposite. but at least you can have a wifi

bakul · 2025-11-20T15:49:53+0000

Bjoern is quite responsive. Do use the wireless mailing list to report.

iwlwifi caused a kernel panic
