--- Comment #8 from Bruno Lago <teolupus at gmail.com> ---
Hi there,

I have just installed the latest drm-tip kernel and can confirm the bug is
still present.

Please let me note that this bug is affecting a lot of people using the Intel
Graphics cards and the latest Linux distributions. This bug is extremely
annoying  for those of us working with two monitors. To reproduce (and cause a
complete freeze / crash of my system) all I have to do is to connect/disconnect
my secondary HDMI monitor a few times.

Here is the version of the kernel I have installed:

bruno at galaxy:~/Downloads$ ls *.deb
linux-headers-4.13.0-994_4.13.0-994.201708042250_all.deb
linux-image-4.13.0-994-generic_4.13.0-994.201708042250_amd64.deb
linux-headers-4.13.0-994-generic_4.13.0-994.201708042250_amd64.deb

Version of the kernel currently in use:

Would be great if Intel could fix this asap. Really annoying to have hardware
that was working well for so many years to behave like this now.

Cheers,
