Subject: Microcode SW errors for Intel 7260
Date: Fri, 04 Jul 2014 20:37:28 -0500	[thread overview]
Message-ID: <53B756D8.1080909@lwfinger.net> (raw)

The wireless device in my new Toshiba Tecra A50 reports the following when using 
'lspci -nnv':

04:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] 
(rev 73)
         Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:4070]
         Flags: bus master, fast devsel, latency 0, IRQ 48
         Memory at e2400000 (64-bit, non-prefetchable) [size=8K]
         Capabilities: <access denied>
         Kernel driver in use: iwlwifi
         Kernel modules: iwlwifi

My kernel is from the wireless-testing tree, and 'git describe' shows

master-2014-06-26-51-g956e5e6

The device seems to work OK, and is connected to channel 36 (5 GHz) with WPA2 
encryption; however, it floods my logs with sequences as follows:
