Once the abort occurs, wifi becomes very unstable, crashing every 5 mins. I've also tested kernel version 3.11.8, using Firmware iwlwifi-7260-7-ucode (ie. version 7) for the 7260 controller. So far, the following commit has helped in dealing with this issue: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=commitdiff;h=6960a059b2c618f32fe549f13287b3d2278c09e9 Looking at dmesg, the failure appears to originate as: [ 398.780636] ieee80211 phy0: Hardware restart was requested [ 398.781020] iwlwifi 0000:02:00.0: L1 Disabled; Enabling L0S [ 398.781158] iwlwifi 0000:02:00.0: L1 Disabled; Enabling L0S [ 398.789161] iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x2000000. Then, after some register values (I can post these if you want), I get: [ 398.789618] iwlwifi 0000:02:00.0: Firmware error during reconfiguration! Abort. [ 398.789622] iwlwifi 0000:02:00.0: FW error in SYNC CMD MAC_CONTEXT_CMD Finally, I get the same warning in util.c: [ 398.789949] WARNING: CPU: 2 PID: 1474 at /home/apw/COD/linux/net/mac80211/util.c:1509 ieee80211_reconfig+0x15d9/0x1860 [mac80211]() Edit: I have since upgraded to kernel 3.13, and although the crash still occurs, iwlwifi tries to restart itself. I can see the wifi icon disconnect and then reconnect automatically a few seconds later.
