on both 1.3.3 and rolling the R8169 driver crashes with the reltek nic on my motherboard (a gigabyte A520I AC)
with this message
rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100)
It then resets itself and the network card resumes until it crashes the next time :)
I installed the following module r8168-dkms and used this git tag for it: https://salsa.debian.org/debian/r8168/-/tree/debian/8.047.05-1 - I used this one because it was the last one that had the 5.4 patch
No more errors in the kernel log and no more broken connections either for the services behind the vyos install.
