    Default Kernel 5.2-rc1 Expecting The Worst: WIFI Dead Overheat No Restart

    We Compiled debian packages of mainline Kernel last night on Deepin 15.10 and followed by Mint 19.1. It was a real disaster.

    iommu=soft does not work anymore = Black screen.

    Replacing it with << ivrs_ioapic[33]=00:00.1 >> works with many side effects: No WIFI network at all , slow, machine overheat and won't restart. In Mintn19.1 we were getting the following notification:

    Running in software rendering mode. Cinnamon is currently running without video hardware acceleration and, as a result, you may observe much higher than normal CPU usage....

    Our laptop won't boot for any Linux ISO images, unless the Kernel is tweaked or edit at boot time.

    <<iommu=soft>> was the best place to be over the last 3 months. So, we are expecting the worst, but BTRF may do it. Some changes were made to ext4, iommu and our WIFI card suppose to have a new driver, but the WIFI network was dead (not shown) in both distros.

    Will see...

    NB We are not using MOK Manager anymore, we do the fresh install with Secure Boot disabled and it works if we re-enable it after compiling mainline Kernel.

    Default Re: Kernel 5.2-rc1 Expecting The Worst: WIFI Dead Overheat No Restart

    Well, we did compile the Kernel a second time to have 2 of them, just in case (default & vanilla). The bug was not there.

    In Yast: Installation Log


    1.Deleting kernel-vanilla
    2.Downloading kernel-macros (download size 218.2 KiB)
    Downloading kernel-devel (download size 11.95 MiB)
    Downloading kernel-source (download size 104.30 MiB)
    Installing kernel-macros-5.2.rc1-1.1.gb33dbfc.noarch.rpm (installed size 20.7 KiB)
    Installing kernel-devel-5.2.rc1-1.1.gb33dbfc.noarch.rpm (installed size 54.84 MiB)
    Installing kernel-source-5.2.rc1-1.1.gb33dbfc.noarch.rpm (installed size 731.70 MiB)

    Restart


    Now we have only one Kernel in the Grub menu. The machine is and was dual boot with 18362.113. Still not shown in Grub.

    Code:
    cat /proc/cmdline
    BOOT_IMAGE=/boot/vmlinuz-5.1.3-1.g4d4d07c-default root=UUID=bba2a465-b011-4074-90f7-4e018c4eaa89 splash=silent iommu=soft resume=/dev/disk/by-id/ata-SanDisk_SDSSDH3256G_183756420226-part7 mitigations=auto quiet

    Gotcha!

    So far, so good!
