[Bug 1262388] Re: 8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly crashes
JamesE, thank you for the requested information. It is understood that
when you test the live environment of both 13.10 and 14.04 it works, but
when installed and it crashes.
Given that according to
http://wireless.kernel.org/en/users/Drivers/iwlwifi your card is
supported on kernel series 3.10.x+, it would be helpful if you tested
the compat-wireless/linux-next development branch noted in
https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-
wireless_from_upstream . Could you please test this and advise to the
results?

Title:
8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly
crashes
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
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.
