Hi,
There is known bug until r3 ARM version. But it is more like losing 20 to 30% of PMU interrupts, not all. http://lists.linaro.org/pipermail/linaro-dev/2011-September/007598.html (read begin and end) http://lists.linaro.org/pipermail/linaro-dev/2011-September/007587.html http://lists.linaro.org/pipermail/linaro-dev/2011-September/007662.html Regards Fred OMAP Platform Business Unit - OMAP System Engineering - Platform Enablement - System Multimedia

Hi all, We are know that the OMAP4460's PMU is buggy, which loses PMU interrupt always. But I do not know what the real bug is, the HW bug or Software bug? What the bug is?
Could some one give a point?
