ETHERCAT WAIT SYNC

Hi at all.
I use normally Debian 10 with ethercat and not have problem.
Now stay testing devian 12 (iso by git linuxcnc with uspace) and Procedure CORBETT ethercat installation
at point 3 and point 4.

When start configuration the value the drive and I/O are refreshed after 10 second after start.
On Dmesg have :ETHERCAT WARNING 0-0 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-1 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-2 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-3 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-4 SLAVE DID NOT SYNC AFTER 5000 MS
:ETHERCAT WARNING 0-5 SLAVE DID NOT SYNC AFTER 5000 MS


AFTER THIS TIME THE REFRESH THE VALUE ARE FAST AND NORMAL OPERATION, BUT NOT UNDERSTAND WHY AT START THE LCNC HAVE THIS WAIT FOR READ DRIVE VALUE.

THE SAME CONFIGURATION WITH DEBIAN 10 AND ETHERCAT 1.5.2 AND LCNC 2.9.0-PRE0 RUN OK
