Some Intel Haswell CPUs are known to have issues with the package C-State PC6 which temporarily disables PCIe, USB, memory controllers - i.e. everything what Intel calls the "uncore". Please try the kernel boot parameter "intel_idle.max_cstate=1" and check if the system becomes stable this way.

With this kernel parameter works perfectly stable tested on 4.1.27 (without this parameter always freeze after few minutes) -- You are receiving this mail because: You are on the CC list for the bug.
