bionic linux-image-4.15.0-47-generic: - Tested with and without efi=novamap and didn't get past the EFI stub messages.
cosmic linux-image-4.18.0-17-generic: - Tested with efi=novamap and the kernel booted and got quite far but then went blank, as expected but this is a good start; without efi=novamap it didn't get past the EFI stub messages. disco linux-image-5.0.0-8.9-generic: - Tested this one for fun, oddly this kernel did worse than 4.18 and didn't get past the kernel stubs either! ** Tags removed: verification-needed-cosmic ** Tags added: verification-done-cosmic ** Tags removed: verification-needed-bionic ** Tags added: verification-done-bionic -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1814982 Title: efi/arm/arm64: Allow SetVirtualAddressMap() to be omitted Status in linux package in Ubuntu: Fix Released Status in linux source package in Bionic: Fix Committed Status in linux source package in Cosmic: Fix Committed Status in linux source package in Disco: Fix Released Bug description: [Impact] The Ubuntu kernel is not currently bootable on various arm64 laptops (HP Envy x2, Asus NovaGo, Lenovo Miix 630, Lenovo Yoga C630, Samsung ...) because of EFI memory permissions/restrictions.
