I am getting this error message at boot on a BeagleBone based on the AM335x (I tried Green and Enhanced) using kernel 6.15.4-bone18 from the Debian I installed using the imaging utility.
The error appears to trigger an error output from function sysc_check_active_timer() with error code -EBUSY. I suspect that it is about the system timer that is somehow misconfigured, or maybe the error logic in ti-sysc.c is somehow wrong. In particular, I don't understand why this error should lead to the probe to fail entirely.
