[Bug 1703091] [NEW] Kernel panic - not syncing: Fatal exception in interrupt

[Joao Luis]

Public bug reported:

I have a Clevo P150SM laptop. Recently, I have frequent kernel panics
"Fatal exception in interrupt".

  Screenshot at https://i.stack.imgur.com/eZRcu.jpg

(I will try to upload the screenshot of the console once I have a bug
number).

It happened the 1st time kernel 4.4.0-83 was installed and since yesterday's package updates was 
happening almost all the time.

Today (the next morning) kernel 4.4.0-83 is booting fine.

The symptons are simular to bug 1702164

(Sometimes it gets far enough to boot the X11 interface - and then crashes, Sometimes it crashes while still in console text mode).
2 leds are blinking: "CapsLock", and the other led which is not NumLock (but I don't know what it is). NumLock is not blinking.

I alread did as root:

    apt clean
    apt install --reinstall linux-image-generic linux-image-4.4.0-83-generic
    update-initramfs -u -k 4.4.0-83-generic
    reboot

but it stays the same.

(The first time I upgraded to kernel 4.4.0-83 the power went down in the
middle of the upgrade, and I fixed the problem more-or-less with the
commands above.).

When it crashes, I manage to boot in 4.4.0-81-generic, and it still
seems to work fine.
