--- Comment #9 from Michael from Offenbach Germany
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.
My system is a small ZBOX nano with an Atom Celeron (N2930, http://ark.intel.com/de/products/81073/Intel-Celeron-Processor-N2930-2M-Cach...), as far as I know these CPUs are "Bay Trail", not "Haswell". Currently I'm working with kernel 4.1.26-1.g8a776b0-default, as advised by Oliver Neukum. No freezes since then, seems to be stable now/again. -- You are receiving this mail because: You are on the CC list for the bug.
