So, I just installed Big Sur 11.3 Beta 5 (I think... I lost track). Anyway its build 20E5217a.   I wanted to try e1000-82545em again as virtio-net was working fine except when I put the system to sleep : on wake I had lost all network.   And so far I do not see the kernel panic I had on previous betas.   I haven't done extended testing yet, but so far so good. And I can put my system to sleep again and not lose network on wake. File transfert from the Unraid server
