    I have been using my X86 for a while now..I have previously used rtc, for rtcwake. the RTC is no longer seen by ubuntu :/ I cant for the life of me figure out what changed.

    Code:
    sean@TreeCam1:/$ timedatectl
          Local time: Thu 2018-01-25 15:34:25 PST
      Universal time: Thu 2018-01-25 23:34:25 UTC
            RTC time: n/a
           Time zone: America/Los_Angeles (PST, -0800)
     Network time on: yes
    NTP synchronized: yes
     RTC in local TZ: no
    
    Code:
    sean@TreeCam1:/$ sudo hwclock --debug
    hwclock from util-linux 2.27.1
    hwclock: cannot open /dev/rtc: No such file or directory
    No usable clock interface found.
    hwclock: Cannot access the Hardware Clock via any known method.
    could the battery have died to produce this error?
    EDIT: its not the battery, just took out my other(brand new) x86 and replaced the battery form that with no success. Just for giggles, I tried the same commands as above on the new machine and got the expected results

    UPDATE! FIXED!
    here's how I did it.. apparently it was a kernel error. So using ukuu I changed my kernel version to 4.10.0 :)

    sudo add-apt-repository ppa:teejee2008/ppa
    sudo apt-get update
    sudo apt-get install ukuu

    sudo ukuu-gtk
    choose 4.10.0 from the list of kernels and install it.. ukuu will take care of grub and everything for you.

    sudo reboot

    Hold shift to enter grub, select Advance Setting and boot into the correct kernel 4.10.0

    and it WORKS!

    at this point I used ukuu to purge the other kernel from the system.

    We are running into this issue to with both Ubuntu 16.04.5 and 18.04.1. Neither allow access to the RTC from the operating system. We purchased around 80 of the x86 advanced boards and have found that about half do not have the RTC preset from the factory. This causes the board to be very slow to boot up and reaching the bios configuration menus. Once the time is set in bios, it seems to boot quickly. We receive the same messages as the original post

    Any update on this? I noticed that firmware 1.06 has been released, are there any release notes for this version?
