Title:
8086:08b1 [Toshiba Satellite P55-A5312] Intel 7260 Wifi regularly
crashes
Status in “linux” package in Ubuntu:
Invalid
Bug description:
My wifi connection is rather unstable in Saucy and Trusty using the
default firmware and kernel. 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. This trace is from
syslog:
