Full Discussion: Server hung, is this a stack trace?
Operating Systems Linux Server hung, is this a stack trace? Post 302885947 by badoshi on Wednesday 29th of January 2014 05:15:09 AM

Thanks Corona,

This is the second time this has occured. The first time HP ASR reset the server, we then disabled ASR hoping that next time around we would be able to get some meaningful messages before resetting the server.

I don' think there's much we can do besides a total blind firmware/patch update (which won't happen!).

IWN(4)							   BSD Kernel Interfaces Manual 						    IWN(4)

NAME

     iwn -- Intel Wireless WiFi Link 4965/1000/5000/5150/5300/6000/6050 IEEE 802.11n driver

SYNOPSIS

     To compile this driver into the kernel, include the following lines in your kernel configuration file:

	   device iwn
	   device pci
	   device wlan
	   device firmware

     You also need to select a firmware for your device.  Choose one from:

	   device iwn4965fw
	   device iwn1000fw
	   device iwn5000fw
	   device iwn5150fw
	   device iwn6000fw
	   device iwn6050fw

     Or you can use

	   device iwnfw

     to include them all.

     Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):

	   if_iwn_load="YES"
	   iwn4965fw_load="YES"
	   iwn1000fw_load="YES"
	   iwn5000fw_load="YES"
	   iwn5150fw_load="YES"
	   iwn6000fw_load="YES"
	   iwn6050fw_load="YES"

DESCRIPTION

     The iwn driver provides support for Intel Wireless WiFi Link 4965, 1000, 5000 and 6000 series of PCI-Express network adapters.  iwn supports
     station, adhoc, and monitor mode operation.  Only one virtual interface may be configured at any time.  For more information on configuring
     this device, see ifconfig(8).

     This driver requires the firmware built with the iwnfw module to work.

EXAMPLES

     Join an existing BSS network (i.e., connect to an access point):

	   ifconfig wlan create wlandev iwn0 inet 192.168.0.20 
	       netmask 0xffffff00

     Join a specific BSS network with network name ``my_net'':

	   ifconfig wlan create wlandev iwn0 ssid my_net up

     Join a specific BSS network with 64-bit WEP encryption:

	   ifconfig wlan create wlandev iwn0 ssid my_net 
		   wepmode on wepkey 0x1234567890 weptxkey 1 up

     Join a specific BSS network with 128-bit WEP encryption:

	   ifconfig wlan create wlandev iwn0 wlanmode adhoc ssid my_net 
	       wepmode on wepkey 0x01020304050607080910111213 weptxkey 1

DIAGNOSTICS

     iwn%d: device timeout  The driver will reset the hardware.  This should not happen.

     iwn%d: firmware error  The onboard microcontroller crashed for some reason.  The driver will reset the hardware.  This should not happen.

     iwn%d: timeout waiting for firmware initialization to complete  The onboard microcontroller failed to initialize in time.	This should not
     happen.

     iwn%d: could not load firmware image '%s'	The driver failed to load the firmware image using the firmware(9) subsystem.  Verify the iwnfw(4)
     firmware module is present.

     iwn%d: could not load boot firmware  An attempt to upload the boot firmware image to the onboard microcontroller failed.  This should not
     happen.

     iwn%d: could not load microcode  An attempt to upload the microcode image to the onboard microcontroller failed.  This should not happen.

     iwn%d: could not load main firmware  An attempt to upload the main firmware image to the onboard microcontroller failed.  This should not
     happen.
