Zeeb from comment #10) I would be glad to add my laptop to the test battery, but I will need a bit of guidance on how a total newbie can run this patched driver (until now I only used FreeBSD on preinstalled dedicated servers, or= on VirtualBox guests). Ideally I'd test it live, with a bit of kldunload / kldload, remaking only = in modules/rtw88 and modules/linuxkpi_wlan. However, this only works for if_rtw88.ko (ifconfig wlan0 down ; kldunload if_rtw88.ko ; kldload /usr/obj/usr/src/amd64.amd64/sys/modules/rtw88/if_rtw88.ko ; sleep 1 ; ifco= nfig wlan0 up) On the other hand, the linuxkpi_wlan.ko materialized in /boot/kernel seems = to be an empty shell, because kldload rejects it with a dmesg telling it's alr= eady part of the kernel (where I find the "skb allocation failed" string by the way). But in the GENERIC conf for the kernel, I see no dedicated setting for linuxkpi_wlan, only the main COMPAT_LINUXKPI switch that certainly should n= ot go away. Do I have any other way than compiling a full kernel to test the linuxkpi_w= lan part? I'd be grateful for any link for an "how-to get linuxkpi_wlan out of the kernel, to a module". Or a simple "no way" so that I go recompile my world without discuss^H^H^H^H^H^H^Hloosing my and your time anymore. --=20 You are receiving this mail because: You are on the CC list for the bug.=
