[<c0477471>] ? printk+0x1d/0x24
[<c01c98f9>] ? perf_prepare_sample+0x269/0x280
[<c0149231>] warn_slowpath_common+0x71/0xd0
[<c01c98f9>] ? perf_prepare_sample+0x269/0x280
[<c01492aa>] warn_slowpath_null+0x1a/0x20
[<c01c98f9>] perf_prepare_sample+0x269/0x280
[<c016e9f3>] ? cpu_clock+0x53/0x90
[<c01cc368>] __perf_event_overflow+0x2a8/0x300
[<c01ccc3b>] perf_event_overflow+0x1b/0x30
[<c01ccccf>] perf_swevent_hrtimer+0x7f/0x120
