Hi Tim and others.  
  
Let's think about this a little differently.  
  
What do we know:  
  
1. You, Ellot and I can build the VM on our respective PIs.  
2.  In general this VM works fine, the only seemingly difference is on a few fonts.  This, of course, is bizarre.   
3. We must be either seeing a difference in hardware, or in software, or in firmware.  
  
Now we start guessing.  
  
1. I use my PI as a server.  I installed Raspberian about 12 months ago, and, the only packages installed on top are samba, and then the 11 packages to make Squeak build.  I'm lazy, I have not checked to see if there was a firmware update nor I have I updated firmware.  
2. I don't know about Ellot, but I have the impression you Tim use your PI more, right?  Do you have more packages installed?  
3.  Or, maybe it's some difference in hardware.  My Pi 3 was bought in early 2019 and has the following dmesg bits.

I have a PI2 sitting around here somewhere.  I'll see if I can get that running...  
  
Any other ideas?  
  
Thanks.
