According to Intel, this bug has been fixed in the microcode updates released in the 20210608 package.
HOWEVER one must go from BIOS to the newest microcode update directly, using kernel early updates. This is how it is supposed to happen by default in Debian (and, AFAIK, Ubuntu nowadays) so it should just work. https://github.com/intel/Intel-Linux-Processor-Microcode-Data- Files/issues/31#issuecomment-876558374 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882890 Title: intel-ucode/06-4e-03 from release 20200609 hangs system in early boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1882890/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
