            Bug ID: 279717
           Summary: iwlwifi stops working with 'Queue 3 is stuck NN MM',
                    Intel AX210 160MHz, REV=0x420
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: wireless

full dmesg

After upgrade FreeBSD 15.0-CURRENT from main-n270474-d2f1f71ec8c6 to
main-n270672-2b887687edc2 I have easely reproduceable crash in iwlwifi.

Wireless driver stops working every time I try to upload some big file to any
host. To reproduce, it's enough to 
    cat /dev/zero | nc -v 192.168.1.xx 9999
    (with nc -v -l 9999 > /dev/null on that host)

pciconf -lv:

It still reproduceable on main-n270710-edbd489d09ba

There is nothing before 'Queue 3 is stuck': the system boots, connects to
network, starts daemons. Right after the login I started netcat and get this
crash.

Experiments: switch extra modules (i915kpi, nvidia_drm, drm_61_kmod) on/off.
Nothing changed, crash is reproducible without these modules.
