    Ubuntu 20.04 is freezing randmply on OMEN by HP Laptop 15-dh0xxx

    Hi,
    I've install ubuntu 20.04 on a brand new OMEN by HP Laptop 15-dh0xxx with geforce RTX 2060, and ssd SAMSUNG MZVLB256HAHQ-000H1.

    Everything is working perfectly, even the RTX demos, wine, etc.. At first I had no sound but after a while it started to work.

    BUT..
    The system is unstable, because ramdomly is freezing... after reboot doesn't reboot, only after many retries.. and again..freeze, reset ten times, freeze..
    No mouse, no keyboard, nothing is working, the image is frozeen, only the power button with x seconds resets.

    I've installed windows 10 to test if the freeze is a harware issue, windows works for days, I had no freeze yet.
    I've run all diagnostic tools I've got,

    I do not know how to get logs to see if the freeze is caused by someting .. audio seems to work or not after many restarts.

    what version of nvidia drivers do you have installed? is this a Intel/nvidia combo or ryzen/nvidia?

    brand new is not always supported by drivers. you could try and load a newer kernel (testing or similar):
    https://itsfoss.com/upgrade-linux-kernel-ubuntu/

    you will need to uninstall nvidia drivers. read carefully:
    https://wiki.ubuntu.com/Kernel/MainlineBuilds

    another option is to try a distro with more up to date kernel like Manjaro for example.
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?
    Full disk backup (newer kernel -> suitable for newer PC): Clonezilla
    User friendly full disk backup: Rescuezilla

    In ubuntu I've installed latest nvidia driver ~450, and the system is freezing too. (I didn't tried the free driver)


    Today I've installed manjaro and system is stable, no freezing yet.. but I didn't had time to test it, I will test next week.

    In manjaro nvidia works as free or nvidia 440 drivers.. (latest is >450, but not available in distro)

    The only problem in manjaro is that the sound is not working. (maybe the sound drivers causes freezing problems), and the booting takes forever.. ~40sec.. (windows boots in 2seconds)

    I do not know where to report this problem, alsa site says something about launchpad..

    Thanks.

    you could try installing Ubuntu and then addign latest kernel (i would say something stable). then if it works, report to launchpad.

    i am not sure what manjaro uses for reporting.

    I've install ubuntu 20.10 beta, and I got into the same problems.
    After that I've check the logs and HDA analog with some text and err -110..with zillion entries.. and that cause all problems.

    I've disable module loading for sound:
    mv /etc/modprobe.d/alba-base.conf .. somewhere

    reboot and I got a stable system and sound works fine, no more freezes.

    Maybe the laptop comes with 2 sounds systems, and the GPU one causes all problems.

    Also nvidia 3d works, system boots in couple of seconds, hdmi works, etc like in windows.

    Thanks.

    For anybody that has the same problem, the solution for me is like this:
    add a blacklist module in the file as root (with sudo)
    /etc/modprobe.d/blacklist.conf
    add line
    blacklist snd_sof_pci
    and the execute
    sudo update-initramfs -u

    this will boot with no problems, and no freezing

    then to activate sound if needed just run
    sudo modprobe snd_sof_pci


    the sound will work, and the system is stable,

    I have a problem with a laptop with it freezing, using Intel/Nvidia.
    Your solution might work, if I can figure out what it is.

    Would you please clearly show what file to be edited, what edits to make? What steps to take to get it working, please.

    Another find is that, if you have no sound and start playing some youtube..
    and activate with modprobe the snd_sof_pci, computer freezes instantly, no mouse, no keyboard.. reset from button

    Another issues is trying to disable the touchpad from settings while sound active, results in a imediat freeze..,
    but the touchpad remains inactiv at next forced reboot.

    Otherwise the system is very stable. but this small issues causes a lot of psyhological pain.

    install ubuntu 20.10 (as it has a better kernel)

    choose ubunut recovery mod from the start
    - drop to root shell

    nice /etc/modprobe.d/blacklist.conf

    at the end of the file add the line:
    blacklist snd_sof_pci
    [save] and exit

    excute
    update-initramfs -u

    to reactivae sound open a terminal and execute
    sudo modprobe snd_sof_pci

    having no application running that uses sound

    All this assuming you have a similar hardware.
