I have same problem with my Dell 11z - similar chipset to the Acer notebooks above - Intel ULV, GMA4500 and Broadcom WiFi.
I reinstalled beta 2 as a clean install and updated and got back to the same problem. Same using Kubuntu. Switch back to 19 and all runs fine.
I have three other desktops that are using 2.6.32-20 without problem.
