[Kernel panic - not syncing: Fatal exception in interrupt]

Thanks. laptop-mode-tools causing the panic. I have disabled them and problem was gone. Will try to fix configuration of laptop-mode-tools.

[Kernel panic - not syncing: Fatal exception in interrupt]

I don't think that the problem in kernel. I have booted with kernel which I use month ago, when there are no such problem. And kernel panic still occurs in the same conditions. I have separate portion only for /home. /usr on the same partition with root.

 

By the way, may be problem some how related to the udev? I think so, because when I boot without power cord connected, panic occurs when 'waiting for udev events'.

This is link to the picture of kernel panic: link

 

I don't use genkernel. I build kernel usnig menuconfig, everything works fine until a few days ago. My kernel config is here: http://pastebin.com/VKp7WBQx

 

This is dmesg: http://pastebin.com/YB63PbBr

 

And this /var/log/everything/current (i am using metalog): http://pastebin.com/j6j7uDQn

 

I have cleared logs, reboot laptop, and then disconnect power cord. This logs from pressing power button and up to kernel panic. I didn't see there any info about crash or so.

 

What else I may do to investigate issue?

[Kernel panic - not syncing: Fatal exception in interrupt]

I need help with fixing 100% reproducible kernel panic on my laptop. This occurs either if I boot my laptop without connected power cord or if I disconnect power cord from already booted laptop. Because of this I think that issue somehow related to the power management system.

 

My kernel is gentoo-sources-3.15.1:

Linux localhost 3.15.1-gentoo #1 SMP Wed Jun 25 21:29:18 EEST 2014 x86_64 Intel(R) Core(TM) i3-3110M CPU @ 2.40GHz GenuineIntel GNU/Linux 

But this issue reproducible with older kernels as well.

 

In boot time panic accours when "populationg udev events". I'm using eudev:

[I] sys-fs/eudev

If someone could help me in fixing this problem? What additional info necessary to investigate issue?
