Thread: Kernel-firmware update 20181026-lp150.2.6.1 locks up system

    Default Kernel-firmware update 20181026-lp150.2.6.1 locks up system

    I updated my system last night, which included a kernel firmware update. This morning, my system wouldn't boot, it just hung on the boot splash screen. Pressing esc did not show any messages. At the time I wasn't sure which update caused it so I did a rollback, rebooted and tried the update again. Same problem. Anyone else having a problem with this update making their system unbootable?

    If I lock the firmware version in yast, do I also need to lock the kernel version?

    Thanks.

    At least, in theory, that should not be needed.

    A package normally lists its requirements. And if a kernel update requires a newer firmware, but you have locked the firmware against updating, then that should also block the kernel update. You might get a "conflict resolution dialog" if you use "Yast" or "zypper" to update -- that would give you a choice between skipping the kernel update or updating the firmware anyway (bypassing your lock). If you use the desktop update applet, it probably doesn't provide a dialog. It might just report a problem and fail to update.

    Yep, that's my wifi card and driver.

    I'm experiencing the same problem on my Alienware machine.

    I have the same problem.
    My Wi-Fi chipset is Killer 1435.

    If you installed the root file system with btrfs, you can do a rollback to a snapshot before you installed the update that broke the system. Select boot from a read-only snapshot from the grub2 menu, then select a snapshot from sometime before the update. Once you're booted into a functional system, in a terminal window enter:

    Code:
    sudo snapper rollback
    which will make the booted snapshot the current one. Then reboot the system normally. After that open up a terminal window and enter:

    Code:
    sudo zypper al kernel-firmware
    which will lock the firmware version and prevent it from updating. Then you should be able to install the other updates without breaking the system.

    If you're not using btrfs, then reverting back to the old firmware will be a little more tricky, and I'm not exactly sure how to go about that.

    I just discovered that the Killer 1435 wlan chip in my notebook is actually a Qualcom Atheros QCA988x chip...

    From this thread

    https://bugzilla.suse.com/show_bug.cgi?id=1121714

    it seems that update "kernel-firmware 20181026" is the culprit.
    Fortunately I can switch of wlan in the UEFI and avoid the kernelpanic.
    I'll download manually the older "kernel-firmware 20180525" and install it to see what happens.

    http://download.opensuse.org/update/...3.1.noarch.rpm

    I'll let you know.

    I can confirm that the latest kernel-firmware update was the culprit.

    Just in case somebody else stumbles over the same problem, here's how I solved it.

    In the UEFI settings I disabled wlan en Bluetooth. That way I was able to boot the system.
    Using another computer, I downloaded the old kernel-firmware here:

    http://download.opensuse.org/update/...3.1.noarch.rpm

    and I copied it to the notebook using a usb-stick.

    Then, on the notebook, in Yast I disinstalled the kernel-firmware.

    (At this point, do not switch-off or reboot your notebook. I don't know what will will happen without the kernel-firmware being present on your system!)

    Then, in the console I installed the downloaded rpm using the command "sudo rpm -i kernel-firmware-20180525-lp150.2.3.1.noarch.rpm"

    I rebooted, went into the UEFI to enable wlan and Bluetooth and everything worked again.

    Regards,

    Great.

    I suggest you lock the firmware to the version that is working. You can do that in Yast Software Management. Search for the firmware, right click on it and lock it from updates. When you manually force an update, after you hear that the problem is solved, that should clear the lock.
