Hi Leonid,
One possible cause I can think of is the trigger type (level vs edge) of an interrupt is incorrect. The Linux device tree should have interrupt type for each interrupt source, so you can change the GIC init code to configure the interrupt types (GICD_ICFGR, assuming GICv2) accordingly and see if the messages disappear.
