Hello Joel,<br /><br />I do get the same, but my understanding is that the RT features are not enabled. I would expect to get:<br /><br />&nbsp; Linux raspberrypi4-64 5.15.34-v8 #1 SMP PREEMPT <strong>RT</strong> Tue Apr 19 19:21:26 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux<br /><br />When I check the .config file in the work folder CONFIG_PREEMPT=y is set but I would expect to see CONFIG_PREEMPT_RT=y instead. <br /><br />That is what you get for rpi4 32 bit as mentioned by Aleksandr above. Is my understanding wrong?
