I have a fix for this problem, however I am seeing this on omap4460
panda. The root cause seems to be that local timer init for OMAP is
using wrong interrupt number. It adds a wrong offset to the interrupt
(OMAP_INTC_START) which should be omitted. Will send a patch soon along
with a new version of core ret set.
