Hi Thomas, It seems I am not the only one with this problem: 2009/9/24 Azraiyl <azraiyl@xxxxxxxxx>: > Same problem here on a Olimex SAM9-L9260 Board (ARM926EJ-S). 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?
