[Bug 1021086] Re: 8086:0091 Kernel Panic when re-enabling wifi via Fn+F2 on Dell XPS 15z
I have a similar but worse problem. I tried to disable wifi and it panicked. Now it panics on normal boot. In recovery console, it panics when enabling networking. If I disable the wifi mac80211 module, it boots but panics when I plug in the mouse or keyboard. The device is an EXO netbook. Reboots do not help. Powerdowns and restats do not help. How do I set this to a state where ir doesn't panic anymore? The work around is this: on panic unplug everything even the AC and remove the battery or wait for it to stop completely. Then perhaps wait five minutes. Dance in a circle saying "Thank you Shawn. I am grateful" three times. Then plug it back in again and restart. To disable wifi, the same procedure would seem to cause fewer problems but I feel you could simply go through the shutdown procedure. I will post later from the computer later for devs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1021086 Title: 8086:0091 Kernel Panic when re-enabling wifi via Fn+F2 on Dell XPS 15z To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1021086/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1482892] Re: Kernel PANIC often when turning WiFi off, on current 3.19.0-27-generic (see text, my be one older), happened before on previous kernel, and one or two, probably more, before that one
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!
