This bug recurred with the last two 20.04 Updater packages, starting mid-September. The initramfs upacking bug 1835660 recurred about the same time. Turning off the Ubuntu splash screen seems to avoid the problem, but when it doesn't (or until you realize that you have to make that change); the spinning logo hang forces a hard power down which seems to cause other problems and affects general stability.
