[Bug 2153556] Re: Kernel regression (6.8.0-117.generic)

We do use it for back-ends on clusters (heartbeat networks) to avoid having to install dedicated switches for this. I believe this even the default recommendation by the Proxmox folks for 3-5 node setups. Hopefully that question is not an omen. -- You received this bug notification because you are subscribed to linux in Ubuntu.

This patch caused mode 3 bonding to completely break on a production cluster. We were able to recover services by booting on a .111 fallback. Hardware is ConnectX-6 at 100G, all interfaces, links and bonding status appear to be up but no packets are passed. Unfortunately, this is a production system so it's now on an older kernel so testing isn't possible. If necessary, I can bring up a pair of VMs to run some tests for this. Thanks!
