WARNING: at kernel/events/core.c:913 add_event_to_ctx+0x5b/0x1c0()

[Tommi Rantala]

Hello,

One of my trinity boxes was not responding, this is what was logged.

The kernel is v3.10-rc4-214-g1612e11 (plus a one-liner NETLINK_MMAP
patch from Patrick McHardy, that I hope is not related to this).

Tommi
