Networking • Not working: BCM4312 802.11b/g LP-PHY

Card: BCM4312 802.11b/g LP-PHY in Dell Inspiron 1545 laptop
Driver requested by the card: bwn_v4_lp_ucode
System: Latest GhostBSD with all updates
hw-probe link: https://bsd-hardware.info/?probe=3c3432b2c0

Upon loading the driver byand connecting to the network, kernel panics and reboots automatically after about 10 seconds since connecting. No changes to rc.conf or loader.conf. Exact steps to reproduce:

• Get BCM4312 802.11b/g LP-PHY card (mini PCIe)
• Install GhostBSD
• save your WPA-PSK network in /etc/wpa_supplicant.conf
• sudo wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf or achieve same result by letting Network Manager in MATE do it
• sudo kldload bwn_v4_lp_ucode
• sudo ifconfig wlan0 down
• sudo ifconfig wlan0 up
• sudo dhclient wlan0 or achieve the same by adding to rc.conf: ipv6_activate_all_interfaces="YES"
• You are now connected, ping and Internet works
• After couple of seconds, GUI freezes, after 10 seconds, reboot

By the way, GhostBSD detects this card (during installation?), so wlan0 and bwn0 are already joined and ready to work, this is done by default in /etc/rc.conf entries, all you need is a bwn driver loaded.

I tried various things, from doing everything by hand without .conf files assistance, to fully loading everything by .conf and wpa_supplicant, tested also in single root mode. Nothing worked, I've tried: no APIC (bricked system), change from DMA to PIO in bwn driver, no ACPI, Safe Mode, siba_load, bhnd_load, and some more, no change anywhere. Every attempt ended up with the same kernel panic. I am not able to copy paste the full error because after reboot I don't know if logs are preserved anywhere?
Lastly, I did not try to recompile the kernel, I don't know how to do it and what I supposed to change there.
