The listing is from a successful boot; the success seems to be when there is a break in the stream of microcode updates. If the logging shows all updates contiguously, the "Microcode Update Driver" line is the last one output before the system freezes. The likelihood of a successful boot has dropped to zero for no observable reason. Any suggestions about what to prevent the freezing?
