Hello, since upgrading to 3.19-rc6-wl (3.19-rc5-wl is working fine). I can no longer use the IWL 3160 in my laptop. As soon as the link goes up (the modules load fine, just ip/ifconfig up), I get this: [ 5.960381] iwlwifi 0000:01:00.0: L1 Enabled - LTR Disabled [ 5.960722] iwlwifi 0000:01:00.0: L1 Enabled - LTR Disabled [ 6.256941] iwlwifi 0000:01:00.0: L1 Enabled - LTR Disabled [ 6.257392] iwlwifi 0000:01:00.0: L1 Enabled - LTR Disabled [ 6.272858] iwlwifi 0000:01:00.0: Microcode SW error detected.
