159.It "iwn%d: device timeout" 160The driver will reset the hardware. 161This should not happen. 162.It "iwn%d: firmware error" 163The onboard microcontroller crashed for some reason. 164The driver will reset the hardware. 165This should not happen. 166.It "iwn%d: timeout waiting for firmware initialization to complete" 167The onboard microcontroller failed to initialize in time. 168This should not happen. 169.It "iwn%d: could not load firmware image '%s'" 170The driver failed to load the firmware image using the 171.Xr firmware 9 172subsystem. 173Verify the 174.Xr iwnfw 4 175firmware module
