    random restarts

    Hello everyone !
    First off, I apologize in advance if someone already posted about the same issue, but a quick search didn't give me anything more relevant than this :
    I'm getting random restarts. Though it didn't affect me much, I lost some work while writing a latex document a few days ago and I'd rather have it fixed.
    I don't think it's related to my PSU as the same machine runs much heavier stuff on Windows 10 without any issue. (X-Plane 11 among other things) and my memory successfully passes memtest86 tests.

    My config:
    • i7 6700k @4.5Ghz
    • Nvidia Gtx 1080 (from Asus)
    • RAM: 24 GB ; 2133 MHz ; CL14
    • Intel 660p SSD (2TB variant)
    • PSU: Corsair CX600
    • Asus Z170 pro-gaming


    Kubuntu 19.04 runs perfectly on my X1 Yoga which is why I suspect a driver issue or something of the sort.

    I checked the syslog and noticed these errors keep showing up: dbus-daemon[1728]: [system] Failed to reset fd limit before activating service: org.freedesktop.DBus.Error.AccessDenied: Failed to restore old fd limit: Operation not permitted
    and thermald[1049]: I/O warning : failed to load external entity "/etc/thermald/thermal-conf.xml"

    the 'sensors' command, with light load (i.e a couple dozen tabs on firefox and libreoffice, TexStudio and Spyder running) -despite the CPU fans running, returns this:
    coretemp-isa-0000
    Adapter: ISA adapter
    Package id 0: +36.0°C (high = +80.0°C, crit = +100.0°C)
    Core 0: +36.0°C (high = +80.0°C, crit = +100.0°C)
    Core 1: +34.0°C (high = +80.0°C, crit = +100.0°C)
    Core 2: +30.0°C (high = +80.0°C, crit = +100.0°C)
    Core 3: +31.0°C (high = +80.0°C, crit = +100.0°C)

    acpitz-acpi-0
    Adapter: ACPI interface
    temp1: +27.8°C (crit = +119.0°C)
    temp2: +29.8°C (crit = +119.0°C)

    asus-isa-0000
    Adapter: ISA adapter
    cpu_fan: 0 RPM
    Could it be a badly configured sensor causing these random restarts ?

    Quick update, in case someone has the same problem. I upgraded to Kubuntu 19.10, and the issue seems to have disappeared.
