Hi,I was trying to use some external hardware interupts on a PPC405 board as part of a hacking session with Jan to bring up the rtcan driver on this board. Here are some versions: Linux Kernel: 2.6.14 Adeos: 1.3-07 Xenomai: from svn (2.3pre, last friday night) The first interrupt interrupt was always fine. When the 2nd interupt occured, it was never handled and did not cause any action. We used the ipipe-tracer and did not see anything related to the 2nd and any further interrupt. I think that the hardware interrupt is somehow masked and therefore never result in any action. So the handling of the first interrupt might be incorrect. This seems to be ppc or even ppc4xx related because I assume that x86 platforms do not have this issue. Is this an Adeos issue. I will do the same test on a 2.4 kernel next week - if nobody tells me that this will be a waste of time.
Could you please add printk statements to the ack, enable and end functions to arch/ppc/syslib/ppc4xx_pic.c if the irq number matches. Please print also SR, ER and status.
