Answering first to note 5, yes.
All the times that kernel 4.4.0-83 crashed, the problem goes away if I boot my
previous kernel 4.4.0-81.
kernel 4.4.0-83.106 does not crash during all the boots. Only some
times. I could not figure out if they are related to cold/hot boots (in
the morning always suceeds, thank goodness), CPU temperature, or any
other factor.
Answering to note 4, regarding the 4.12.0-041200.201707022031 kernel it
appears to solve the problem, but I can't be 100% sure.
Using the grub Advanced Ubuntu options, I performed 12 reboots, 6 reboots of
each kernel 4.4.0-83.106
and 4.12.0-041200.201707022031 interleaved (boot 4.4.0-83.106, then reboot
4.12.0-041200, then reboot 4.4.0-83.106, etc...)
Kernel 4.4.0-83.106 crashed on boot (with the same error) 3 out of 6
times.
Kernel 4.12.0-041200 crashed 0 (zero) out of 6 times.
Not all reboots took a 5 second power-off interval. (The ones that kernel
4.4.0-83 crashed, did wait a few seconds before booting again).
So, the fix looks promising.
Meanwhile, I go back to kernel 4.4.0-83 or 4.4.0-81 because I need virtualbox
(but I leave 4.12.0-041200 installed for now).
For my own record, the procedure I followed to install the 4.12.0-041200 was:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-
headers-4.12.0-041200_4.12.0-041200.201707022031_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-
headers-4.12.0-041200-generic_4.12.0-041200.201707022031_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/linux-
image-4.12.0-041200-generic_4.12.0-041200.201707022031_amd64.deb
sha1sum *.deb # sums looked ok
# as root (su -) from now on
dpkg -i *.deb
# ...
# ERROR (dkms apport): kernel package linux-headers-4.12.0-041200-generic
is not supported (twice)
# ...
# lots of W: Possible missing firmware /lib/firmware/nvidia/...
But it did boot fine afterwards. (I did not attempt to remove or run
virtualbox).

Title:
Kernel panic - not syncing: Fatal exception in interrupt
Status in linux package in Ubuntu:
Incomplete
Bug description:
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.
