[Bug 2044203] Re: Cannot boot after update intel-microcode

[Alex Murray]

Thanks - yes I understand. This is the first such report that I have
seen of problems with these newer microcode versions against this
particular CPU - looking at the upstream Intel issue tracker
https://github.com/intel/Intel-Linux-Processor-Microcode-Data-
Files/issues I can't see anything similar either. Unfortunately there is
not a lot we can do in Ubuntu about this as this package is provided as
a binary blob direct from Intel.

Out of interest, can you please ensure you have the latest BIOS updates
installed for your machine and see if this helps?

Also you could try reporting this issue upstream directly with Intel to
see if they can provide any assistance.

Title:
  Cannot boot after update intel-microcode

Status in intel-microcode package in Ubuntu:
  New

Bug description:
  I am using Ubuntu 22.04.3 LTS, the kernel version is 6.2.0-36-generic. My CPU is Intel® Core™ m3-7Y30.
  The intel-microcode_3.20230214.0ubuntu0.22.04.1_amd64 works fine on my computer, but the computer cannot boot if I update the package to later versions (3.20230808.0ubuntu0.22.04.1 and 3.20231114.0ubuntu0.22.04.1). There is no output on the screen, it is light but just purely black. In case the computer fails to boot, I have to boot into the recovery mode (the hardware GPU was disabled and CPU graphic driver was used in this case), and fall back the intel-microcode package to version mentioned at the beginning (3.20230214.0ubuntu0.22.04.1).
