Hi,

Thanks for the quick answer

That means I will reset the bisection. Right? Is there any other info we
can extract from there?

So Do you want me to test 4.3 or 4.4-pre/rc*/latest linus tree. I assume
4.3 for now.

I will do it later tonight. It will take 2 days at least to report back

It is an i7
Motherboard: ASROCK H97 PRO4 RETAIL
CPU INTEL CORE I7-4790 3.60GHZ LGA1150 - BOX
It has 16GB of RAM, one SSD and one HDD
I have NO external graphics card

Do you want me to run something on this like lspci, lsusb

I upgraded the BIOS of the motherboard to the latest. This is not the
problem though because I upgraded after the problem occurred as a counter
measure in case I was hit by a buggy BIOS and linux had changed its
behavior to be stricter.

I experimented with ACPI compilers/decompilers and I was tempted to fix my
ACPI tables but I didn't.

I saw the kernel command line option acpi_os=!Windows2013 but I didn't try
it. Do you thing I should try it?

I would like this to be fixed so I am willing to do the testing.
