Got the following warning: [ 14.714533] WARNING: CPU: 0 PID: 823 at arch/x86/include/asm/fpu/internal.h:163 fpu__clear+0x8c/0x160 [ 14.726603] Modules linked in: [ 14.729910] CPU: 0 PID: 823 Comm: kworker/u2:0 Not tainted 4.5.0-rc7-next-20160310+ #137 [ 14.738307] 00000000 00000000 ce691e20 c12b6fc9 ce691e50 c1049fd1 c1978c6c 00000000 [ 14.747000] 00000337 c196b530 000000a3 c102050c 000000a3 ce587ac0 00000000 ce653000 [ 14.755722] ce691e64 c104a095 00000009 00000000 00000000 ce691e74 c102050c ce587500 [ 14.764468] Call Trace: [ 14.767172] [<c12b6fc9>] dump_stack+0x16/0x1d [ 14.771889] [<c1049fd1>] __warn+0xd1/0xf0 [ 14.776253] [<c102050c>] ? fpu__clear+0x8c/0x160 [ 14.781234] [<c104a095>] warn_slowpath_null+0x25/0x30 [ 14.786648] [<c102050c>] fpu__clear+0x8c/0x160 [ 14.791447] [<c101f347>] flush_thread+0x57/0x60 [ 14.796341] [<c113a5cc>] flush_old_exec+0x4cc/0x600 [ 14.801594] [<c117ab20>] load_elf_binary+0x2b0/0x1060 [ 14.807010] [<c1111220>] ? get_user_pages_remote+0x50/0x60 [ 14.812898] [<c12c4687>] ? _copy_from_user+0x37/0x40 [ 14.818236] [<c1139f82>] search_binary_handler+0x62/0x150 [ 14.824007] [<c113b19c>] do_execveat_common+0x45c/0x600 [ 14.829647] [<c113b35f>] do_execve+0x1f/0x30 [ 14.834289] [<c1059941>] call_usermodehelper_exec_async+0x91/0xe0 [ 14.840765] [<c17f2310>] ret_from_kernel_thread+0x20/0x40 [ 14.846540] [<c10598b0>] ? umh_complete+0x40/0x40 [ 14.851626] ---[ end trace 137ff5893f9b85bf ]--- Is it know issue?
