Intel Nuc 10/I219-V e1000e hardware hang

[md127]

I've switched off all offloading as per this post. But I can confirm that this doesn't solve the issue anymore. I'm on kernel pve-kernel-5.13.19-4-pve: 5.13.19-9
Syslog is intermittently filled with these messages. I can't do bulk data transfers through the network interface; As soon as I try a sustained outbound bulk data transfer, it fails with the connection resetting and syslog says:

seeing the same hang & reset issue on the I219-V on an ASUS PRIME_H510M-A motherboard.
I'm running PVE7.1-12 | Kernel 5.13.19-6-pve

Thank you for sharing. I have the same exact error.

my /etc/network/interfaces already has vmbr0 set as inet static, should I be adding and additional `iface eno1 inet static` with the suggested `post-up /sbin/ethtool -K eno1 tso off gso off` configuration ?
