Here I am in 2017, and it seems to be a regression bug. A bug that has come back, or perhaps it was never fixed and the user who reported it fixed, did so because it went from always crashing to intermittent crashing. A user will learn not to turn off wifi and the panics stops but the bug lurks away. I am using an Exomate and not only does it panic when turning off wifi but on startup it panics intermittently whenever you use a USB device you left plugged into it or plug in a USB device. After many power cycles and with periods of remaining off, the perpetual panics abate but I know not to turn off wifi now.
See also: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/404626?comments=all As a user, I am getting similar symptoms. Although the cause may not be same, people are going to go there first when they search, so am linking to here from there. This is a cheap netbook for Students. Free for Students in Argentina and their teachers. The hardware is from a similar year. There are hot keys combinations that do various things using a special 'fn' key you use in conjunction with keys f1 through f10. One is (Fn+F2). If I use the GUI or Fn+F2 to turn off wifi, it kernel panics. # uname -a Linux Exomate-X352 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:08:14 UTC 2014 i686 i686 i686 GNU/Linux # dmesg | tail [ 1.544827] fb0: VESA VGA frame buffer device [ 1.544880] intel_idle: MWAIT substates: 0x20220 [ 1.544895] intel_idle: v0.4 model 0x1C [ 1.544900] intel_idle: lapic_timer_reliable_states 0x2 [ 1.544905] tsc: Marking TSC unstable due to TSC halts in idle states deeper than C2 [ 1.545040] ipmi message handler version 39.2 [ 1.545770] ACPI: AC Adapter [AC0] (on-line) [ 1.545982] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0A08:00/PNP0C0D:00/input/input0 [ 1.546020] ACPI: Lid Switch [LID] [ 1.546150] input: Power Button as /devices/LNXSYSTM:00/device:00/PNP0A08:00/PNP0C0C:00/input/input1 [ 1.546180] ACPI: Power Button [PWRB] [ 1.546427] input: Sleep Button as /devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input2 [ 1.546437] ACPI: Sleep Button [SLPB] [ 1.546692] input: Power Button as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input3 [ 1.546701] ACPI: Power Button [PWRF] [ 1.551281] thermal LNXTHERM:00: registered as thermal_zone0 [ 1.551288] ACPI: Thermal Zone [TZ01] (32 C) [ 1.551362] GHES: HEST is not enabled!

Status in linux package in Ubuntu: Expired Bug description: When opening lots of network connections and disconnecting from WiFi I get two light blinkning (CAPS LOCK light and the one to it's right) - assuming kernel PANIC. [As Google Chrome opens a lot of tabs, when starting, I've used the trick of disconnecting WiFi for a while (and sometimes killing Chrome processes, but not this time I believe, but it shouldn't matter), to get it to avoid OOM.] This is not the first time I've gotten a kernel PANIC this way or the only kernel (may be a few versions back). I assume this is a bug in the kernel (also), but also in (proprietary) wl: lsmod |grep wl wl 6369280 0 cfg80211 540672 1 wl syslog: Aug 8 16:59:18 Ryksugan dnsmasq[826]: setting upstream servers from DBus Aug 8 16:59:18 Ryksugan whoopsie[680]: [16:59:18] Cannot reach: https://daisy.ubuntu.com Aug 8 16:59:18 Ryksugan kernel: [ 2554.480178] cfg80211: World regulatory domain updated: Aug 8 16:59:18 Ryksugan kernel: [ 2554.480184] cfg80211: DFS Master region: unset Aug 8 16:59:18 Ryksugan kernel: [ 2554.480186] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp), (dfs_cac_time) Aug 8 16:59:18 Ryksugan kernel: [ 2554.480190] cfg80211: (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) Aug 8 16:59:18 Ryksugan kernel: [ 2554.480192] cfg80211: (2457000 KHz - 2482000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) Aug 8 16:59:18 Ryksugan kernel: [ 2554.480195] cfg80211: (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm), (N/A) Aug 8 16:59:18 Ryksugan kernel: [ 2554.480197] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) Aug 8 16:59:18 Ryksugan kernel: [ 2554.480200] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm), (N/A) Aug 8 16:59:18 Ryksugan NetworkManager[737]: <info> NetworkManager state is now DISCONNECTED Aug 8 16:59:18 Ryksugan NetworkManager[737]: <warn> Connection disconnected (reason -3) Aug 8 16:59:18 Ryksugan wpa_supplicant[792]: wlan0: CTRL-EVENT-SCAN-STARTED Aug 8 16:59:18 Ryksugan dbus[745]: [system] Activating via systemd: service name='org.freedesktop.nm_dispatcher' unit='dbus-org.freedesktop.nm-dispatcher.service' Aug 8 16:59:18 Ryksugan NetworkManager[737]: <info> (wlan0): supplicant interface state: completed -> disconnected Aug 8 16:59:18 Ryksugan systemd[1]: Starting Network Manager Script Dispatcher Service...
