Your "fix" helps > aswell. Can you please give me some advise here on this problem? Should it work with the recent RT-patchset to share an interrupt line between the NODELAY and the threaded domains? Notice that moving the interrupt handler of the atmel serial driver to the NODELAY domain works stable. I could provide a patch for it, but that would mask the root cause of this problem, so I would prefer debugging it first before patching it... What do you think? Kind regards, Remy
