Could you share us how you reproduced the problem? and which kernel are you used to reproduce it?
The kernel is Linus' tree (bb4c7e9a9908548b458f34afb2fee74dc0d49f90), .config is attached. HW is Panda board (OMAP4430). Reproduced by just starting oprofile:
opcontrol --vmlinux=vmlinux opcontrol --start
then waiting a few seconds to hit an unhandled IRQs threshold.
Thanks, Dmitry
