finally i install again LMDE6 .... these time choose "english" language at installing menù .... after installation I run process for rt-preempt kernel activation .... after these i update firefox .... update graphical libs .... update all libs required by linuxcnc .... than istall again Lcnc 2.9.2 from my USB disk .... udate and upgrade again .... and after i use procedure described dy Rodw for ethercat .... these time it is installed and work ..... last time during istallation steps I choose my narural language ... and at least somethings fails. Same as 5 years ago when try for first time lcnc on debian.
After these on these machine (adler lake N95) I try for a while new LMDE 6 rt with ehtercat "hystogram latency at 1ms" with good result .... actually after dmesg -C command and after 1 hour hystogram test running, i read these from dmesg:

1- flow control off think normal ... but LMDE6 every 5min show me messages about "enp3s0 failed activating connection " with annoing pop-up whindows on top-right of desktop (enp3s0 is ethercat connection ) ....
2- after these " [ 1577.746895] perf: interrupt took too long (3961 > 3937), lowering kernel.perf_event_max_sample_rate to 50250 " ..... never check before .... is normal??
some one can suggest me solution for point 1) and suggest to me something about point 2)? .... can be normal point 2) or something is not ok?
regards
