Crash during reboots

  • Hi everyone, lately i am having some crashes during reboots and i would like to ask you if anyone is kind enough to look at the log in the file and tell me what the problem would be.
    Thank you very much to those who can help me.

    Does it always fail in the same way?

    That sort of crash can be hard to pin down. If it doesn't fail the same way each time I would look at bad ram.


  • It crashes more frequently during reboots, but it also happens when I turn it on normally after cleaning.
    The system is on a machine and is not virtualized.
    How can I provide you with further details to identify the problem?
    Thank you.

    The important question there is if the crash reports are similar or identical even.

    If they are it may be a software issue. If they are different every time it's probably a hardware problem, most likely bad ram. Though if it was I might expect it to crash at random times not just at boot.
