Since 6.12 came out I have been following the forum hoping for a solution to 6.12 random shutdowns / freeze-ups and network issues. I tried 6.12, up to 6.12.3 and still had to go back to 6.11.3. I have 7 different Unraid machines and all but 2 are on different hardware. I have tried upgrading my Chenbro 12000U home server and another one built in a Dell T3500. Both have had the same random shutdown / freeze-up issue (likely due to "macvlan call traces found" errors). The most common recommendation has been to switch to ipvlan in docker. The problem with that change is that custom networks are toast unless you add another network adapter. Really?! I have to add new hardware to get around a problem that started with an Unraid upgrade?

 

Can someone please help me to understand what is going on? Macvlan works fine on Unraid 6.11.3. Does anyone know what was changed in Unraid 6.12 that is causing these kinds of issues to a wide range of hardware setups? Is this a bug? Is anyone looking into solving the root issue behind this so that weird workarounds are not necessary? I am freely admitting that I may have missed the posts addressing this. Just point me in the right direction.

 

Thanks.

Wait for v6.12.4, that will have a new option to keep using macvlan.

Thank you so much for the update. Any idea what has been causing the issue? (Just curious 😁)

It's an old Linux kernel issue, it's been happening since v6.4, but apparently with each newer release it affects more users.
