VMware Fusion 12 on Big Sur cpu stalls

I‘ve been using a Linux virtual machine (Home Assistsnt) on VMware Fusion 11 (Catalina) for a while and it worked flawlessly. A couple of weeks ago I upgraded all my machines to Big Sur and moved to Fusion 12.

The VM boots ok, but every 3 hours (and it seems to be very regular) the cpu usage rises over a few minutes to 100% and there‘s an rcu detected cpu stall. There‘s no memory problem / leak and I‘ve tried numerous combinations of # cpus / memory / machine type / compatibility etc. Tried generating error reports but VMware just hung...

After a frustrating week I thought I‘d try Parallels as an alternative and the same VM (just converted, only had to change network adapter) worked perfectly with no cpu stalls. What is going wrong with VMware?

Other issue is that bridged networking corrupts packets (both under VMware and Parallels), but shared networking works...

Would like to make this work again with VMware, but have run out of ideas. The cpu stalls show no stack dump and, as I said before, the same VM works fine with Fusion 11 (Catalina) and Parallels (Big Sur).

As this may be hardware related it would be beneficial to post details of what you are using.
