Trying to run some newer software, so I upgraded to bullseye (Debian testing). I expected some trouble, so I was somewhat surprised, but after the upgrade my bela process seems to run fine! I use a cross compiler to build my bela project on another debian machine, and I didn't test the web UI, but the bela process itself seems to work.
Now I'm getting these in dmesg, regularly, roughly twice per second or so:
[Wed May 26 18:33:46 2021] [Xenomai] bad syscall <0x197>
[Wed May 26 18:33:46 2021] [Xenomai] bad syscall <0x197>
[Wed May 26 18:33:47 2021] [Xenomai] bad syscall <0x197>
[Wed May 26 18:33:47 2021] [Xenomai] bad syscall <0x197>
syscall 0x197 (407) seems to be clock_nanosleep_time64 on arm: https://marcin.juszkiewicz.com.pl/download/tables/syscalls.html
So even if the bela process seems to work, I would like to find out what this message is about and if possible get rid of it, at least for the log spam. Any chance I could build a newer kernel? Xenomai? I'd appreciate any hints.
