Hi, my wifi connection is rather unstable on my Toshiba P55-A5312 laptop
which uses an Intel 7260 (rev. 73) wireless network controller. Once the
abort occurs, wifi becomes very unstable, crashing every 5 mins.

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]()

This is on kernel version 3.11.8, and I am using Firmware
iwlwifi-7260-7-ucode (ie. version 7) for the 7260 controller.

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.  This
trace is from syslog:

I have saved away dmesg and syslog output if you require it.

Thanks!
