CPU is Intel Broadwell i7-5775C . OS Kubuntu 15.04, Linux kernel 4.2unstable version If enable and compile a software, it will cause hardware crash. But, if disable SpeedStep and Turbo Mode in BIOS, this issue will not happen. -- You are receiving this mail because: You are the assignee for the bug.
