    Brought to emerg. mode due to unsupported optional feature

    Hi,

    Right after installing SLED 15 I tried to boot it and I get taken to emergency mode with the error:

    Code:
    PKCS#7 signature not signed with a trusted key
    Couldn't mount %sbecause of SUSE-unsupported optional feature %s. Load module with allow-unsupported=1.EXT4-fs (sdb1): METADATA_CSUM
    . Must admit my experience with SLED 15 hasn't been too positive so far, frankly for a paid product it's doing poorly compared to its free counterpart, openSUSE Leap, but please feel free to help me turn that around as I'd love to be proved wrong! By-the-way, I know the error message might make it sound like I tried to boot it using another distro's bootloader and that said bootloader was trying to boot it with different options to that which it supports, but no I booted it via its own bootloader (UEFI), sled-secureboot. So how do I fix this error? Is it like a kernel option I add to its GRUB entry?

    Thanks for your time,
    Brenton

    Hi
    No, just a little more restrictive for support so somethings are off
    by default

    Maybe check out the release notes for another gotchas?
    https://www.suse.com/releasenotes/x86_64/SUSE-SLED/15/

    Add the parameter to either module loading (via grub kernel options),
    system wide via editing /etc/modprobe.d/10-unsupported-modules.conf or
    adding your own say /etc/modprobe.d/20-ext4.conf;
    Code:
    options allow_unsupported=1
