--- Comment #10 from fedang <code@fedang.net> ---
Hello, I found a similar crash on my Thinkpad T14 (Comet Lake PCH-LP CNVi
WiFi), both on 15-RELEASE and 15-STABLE.
Hardware probe: https://bsd-hardware.info/?probe=beae9b0886

The null dereference can be easily reproduced by connecting and disconnecting
in quick succession.

The affected code seems the same:
#8  lkpi_sta_auth_to_scan (vap=0xfffffe010fb3c010, nstate=<optimized out>,
arg=<optimized out>)
    at /usr/src/sys/compat/linuxkpi/common/src/linux_80211.c:2612
2612            ni = lsta->ni;                  /* Reference held for lvif_bss.
*/
