There has been some > work related to this topic after 4.2 (large page pat handling done by > Toshi Kani and mtrr/pat handling by Luis Rodriguez). 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.

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? > Wow! Thanks for doing this work! > I would like this to be fixed so I am willing to do the testing. Vassilis
