Hi to all!
I can unfortunately confirm this "unknown main item tag 0x0" error also for Kubuntu 20.04 and kernel 5.11.0-27. The used hardware is an Apple Magic Mouse 2 at an iMac8,1. It should be noted that Kubuntu is running in native (U)EFI mode, not in legacy CSM Bios-emulation. Maybe this fact has here some relevance. The coresponding dmesg output regarding this issue looks as follows:
