--- Comment #4 from Konstantin Belousov <kib@FreeBSD.org> ---
(In reply to joss.upton from comment #3)
Could you please provide exact recipe to reproduce the overflow panic ?

I tried e.g. pmcstat -P CPU_CLK_UNHALTED_CORE <some looping binary> on
sandybridge and was unable to panic stock HEAD kernel.
