159The driver will reset the hardware. 160This should not happen. 161.It "iwn%d: firmware error" 162The onboard microcontroller crashed for some reason. 163The driver will reset the hardware. 164This should not happen. 165.It "iwn%d: timeout waiting for firmware initialization to complete" 166The onboard microcontroller failed to initialize in time. 167This should not happen. 168.It "iwn%d: could not load firmware image '%s'" 169The driver failed to load the firmware image using the 170.Xr firmware 9 171subsystem. 172Verify the 173.Xr iwnfw 4 174firmware module is present. 175.It "iwn%d: could not load boot firmware" 176An attempt to upload the boot firmware image to the onboard microcontroller 177failed. 178This should not happen. 179.It "iwn%d: could not load microcode" 180An attempt to upload the microcode image to the onboard microcontroller failed. 181This should not happen. 182.It "iwn%d: could not load main firmware" 183An attempt to upload the main firmware image to the onboard
