Jamulus server on PREEMPT_RT causes lxpanel to use 100% CPU #8

Closed kdoren closed 3 years ago

kdoren commented 3 years ago

Jamulus server with multithreading enabled is not stable with my PREEMPT_RT kernel build on RPi4. It will eventually trigger lxpanel to go to 100% CPU on one of the cores. This can be avoided by running low-latency PREEMPT kernel instead of PREEMPT_RT, or by running jamulus server without multithreading.

I don't know if this is a general problem with PREEMPT_RT, or is specific to my build for RPi4.

Initial testing indicates that release 5.10.52-rt47 (see releases) seems to fix the issues with Jamulus server locking up on earlier versions of PREEMPT_RT kernel 5.10.
