not sure if that can be related to the incident:
I just move like 20 GB from a NvME device to the same device...
the system was laggy, it take almost 30 seconds to move the next 16 small
files
when it finnish surely the cache (disk or system) and during that time I
see the
message "Ethernet disconected" on the Mate interface and that is what I can
see
on the output of DMESG (The computer still working isn't crashing)
Then I send the "test" to DMESG and I switch to the root user, and I come
back
to the normal user

btw, sorry I can't send much more information but I don't know how to get
more.
=============
I get too many lines of that type but didn't show too many info with
different
number than 64
[76635.140106] kauditd_printk_skb: 64 callbacks suppressed

It's possible to get it more verbose ?
=================
I still have the SSD in this status just if I need to make any other test
on the
computer in the shop, at home I will try to move it into a VM to do more
tests.
I create several VMs with Debian 12.13 13.00 13.01 13.02 and 13.03 to see if
what files change from one version to another and see the status of my
systems

I have a sparse NvME so isn't a big problem for me to keep it like that


Regards
Z80user (David)
=================
that is the DMESG
