I hit a possible regression in kernel 6.4.x, it seems to me that this is a very
similar (or same) issue like bsc#1106833 and similar. After some time
(depending on the network usage, usually within 24 hours) the kernel panic
happens and the network interface becomes unusable (in fact it probably
generates some nonsense on the line as it also takes down the whole network
segment).
This behavior can be observed in 6.4.3-1-default, 6.4.6-1-default,
6.4.9-1-default and now in 6.4.11-1-default. The issue is not happening in
6.3.9-1-default which I am using right now as a workaround.
