Well, I'm not clear on the limitations of live ISOs but since you were
able to install linux-
image-4.14.0-041400rc5-generic_4.14.0-041400rc5.201710152230_amd64.deb,
it shouldn't be any harder to install the .deb for intel-
microcode-3.20170707.1~ubuntu17.04.0 or newer. I suppose try rebooting
How do I go about it? Consider me being a Windows GUI having the live

Your 4.12 also freezes the system. No additional output with Ben's

That's where I took my kernels from. And the earliest 4.13 in there is
4.13.0-041300rc1-generic as I already said in #3!!!
In #15 I was asking for something in between 4.12.14-041214-generic and
4.13.0-041300rc1-generic.

Please find the first version of v4.13-rc* that has this regression.
