    NUC6i3SYK - Machine check exception - no boot

    rk75muc

      Hi!

       

      For the past eight weeks, I have been happily running a NUC6i3SYK with Xubuntu 15.10 as a media player/HTPC. Memory modules are 2 x 4GB Crucial CT4G4SFS8213 DDR4-2133 and SSD is a Transcend TS128GMTS800. BIOS version is 0028.

       

      Everything has been fine, no problems whatsoever regarding software or hardware. The machine has been running 24/7 for the last about 4 weeks.

       

      Recently, the machine hung itself, and when rebooting, it enters the GRUB menu. From there trying to boot normally into Linux results in a reboot, ending once more in the GRUB menu. The same happens when rebooting in recovery mode, however, it get a bunch of messages prior to reboot, the final ones of which read as follows (timecode removed):

      mce: [Hardware Error]: Machine check: Processor context corrupt

      Kernel panic - not syncing: Fatal Machine check

      Kernel Offet: disabled

       

      What I did so far is:

       

      1. Run IPDT for UEFI, showing no errors, but a warning to the effect that the clock speed is too high (3 GHz). I did not do any overclocking or the like.

       

      2. Run Memtest86 for each memory module separately, four full passes, showing no errors.

       

      3. Tried to boot into various live images (Knoppix 7.0, Xubuntu 15.10, IPDT under Fedora, SystemRescueCD), however, the system hangs itself at some point during boot.

       

      BIOS has been reset to standard values prior to the above.

       

      What I will do next is put the SSD into my PC and run some checks on it. However, since I cannot boot any live images, I do not think it is a SSD/file system-related error.

       

      So, does somebody have any ideas what might be the problem and what I might do to solve it (short of getting a replacement unit)?

       

      Thanks, Robert
