>Description:
Since 9.0-RELEASE I am not able to bring the wireless card up.
dmesg shows the following errors:

iwi0: timeout processing command blocks for iwi_bss firmware
iwi0: could not load main firmware iwi_bss

The computer is a Clevo D400K. Since 7.0 up to 8.2-RELEASE the wireless worked without problems (besides the known firmware limitations and so).

Here[1] there is more information about the problem and the steps I followed to try to fix it.

I get the error also with the GENERIC kernel. My loader.conf contains the following lines:

wlan_load="YES"
firmware_load="YES"

iwi_bss_load="YES"
iwi_ibss_load="YES"
iwi_monitor_load="YES"

As suggested, this could be ACPI related since deactivating ACPI in the bootloader results in a panic coming suspicioiusly from the iwi_detach function. No core is generated despite I have the proper configuration (crash too early?)

>How-To-Repeat:
Boot with the GENERIC kernel and the loader.conf suggested above.

After that, create a wlan0 device:

ifconfig wlan0 create wlandev iwi0

And then try to bring it up

ifconfig wlan0 up
