[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Kai-Heng Feng (kaihengfeng)]

Please update the system and see it's solved there. Probably a regression introduced by intel-microcode.

[Bernard Moreton (bernard-moreton-1)]

The system has been updated several times since, with no further problem.
I note that this was the only time that two kernels have been downloaded together, and I guess that may be the cause of the problem?
I held on to the previous kernel, and used that until a fresh kernel appeared, and did not delete it until a further kernel got downloaded.
Please mark this bug as completed - fixed by time, if by nothing else
