Hi, If configuring chrony sources to PHC and NTP, and while PHC is the current chosen source, In case PHC source returns zero timestamp (get_phc_sample<https://github.com/mlichvar/chrony-nts/blob/master/sys_linux.c#L694>) Chrony will validate the timestamp, calculate the source score and will switch to a better source (NTP) as expected But in case PHC source returns a failed status (for example -EIO) Chrony will not switch the sources and will stay on PHC source for an infinite time Although Chrony debug logs indicates the error: sys_linux.c:859:(get_phc_sample) ioctl(PTP_SYS_OFFSET) failed : Input/output error
Is that a wanted behavior? Thanks
