Hi Alexandre,

> Preemp-rt on at91 has multiple issues:

I'd like to use Linux RT on a Acme Arietta (AT91SAM9G25). I tried
4.4.1-rt6, but it does not boot, I get absolutely no message on the
debug port interface. I'm a complete newbie on Linux RT, so I may well
have done something wrong, but the same kernel config without
CONFIG_PREEMPT_RT runs fine.

I'm a bit confused about what is needed for running 4.4.1-rt6 on this
board: it seems some of your patches got merged, could you please
clarify the situation? Are there some peripherals not supported (I
mainly need ADC and PWM)?

Thanks,
