    Hi, forum.

    I have elementary OS (based on 14.04.1-Ubuntu) installed on a laptop. When unplugged, system crashes, and only a black screen appears. When launching in safe mode from Grub, the same log is seen:

    Code:
    [ 1336.668635] BUG: unable to handle kernel NULL pointer dereference at 0000000000000001
    IP: [<ffffffff8143e7b4>] acpi_idle_enter_bm+0x48/0x23a
    [ 1336.668803] PGD 78083067 PUD 78084067 PMD 0
    [ 1336.668848] Oops: 0000 [#1] SMP
    ...
    (similar lines with colons here)
    ...
    [ 1336.672569] drm_kms_helper: panic occured, switching back to text console
    
    
    .

    I tried boot-repair in reinstalling Grub: nah, it seems that the issue is with the kernel (3.160-46-generic), very specific though. I tried reporting a bug on Launchpad: seems that me alone I have this problem(

    Does anybody know, if there's a way it can be solved? Are there any other forums, users of which can catch the thing? Please help.

    It looks like you have a bad kernel installation, most likely caused by either corrupt package downloads or (if this is a recent installation) a bad ISO. Can you redownload, check the MD5SUM of the ISO, and reinstall elementary?

    Official Elementary OS support is provided on stack-exchange but we can help also. ;)

    you can copy /boot from the same os and paste them to /boot.(i have not tried it, but it might work).
    you configured kernel wrong!
    i meet the same problem when i tried to upgrade kernel to 4.3.3
