Hello , Thanks , tommylight found me a 2.9 version under linux mint 21 that works great on my PC with a relatively stable rtpreempt kernel .
My PC was not working at all with Debian and kernel 4.19 ... .
I invite everyone to switch to this version, in addition Linux mint is much more flexible and more modern than Debian 10.
The Mint 21 version is a beta version, but for having tested it in all the directions, I did not succeed in crashing it.
Thanks again to all the team for your help and assistance
