Thank you very much for the information, and I apologize for not noticing the old BIOS. I have updated BIOS to the newest one:
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date L77 Ver. 01.33 07/20/2015 I am not sure what causes this bug to reproduce, so I will wait for the bug to manifest on its own.
