[Kernel-packages] [Bug 1814982] Re: efi/arm/arm64: Allow SetVirtualAddressMap() to be omitted
Note: if the point release installers will pick up the 4.18 series kernel with the fix then I think a fix for cosmic will suffice vs. bionic also given the results. -- 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.

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.

[Kernel-packages] [Bug 1814982] Re: efi/arm/arm64: Allow SetVirtualAddressMap() to be omitted
Snapdragon 835 Laptop Results: 4.15 boots to the first 4 lines before kernel 4.18 boots most of the kernel, stops for a bit, then suffers with an rshed crash 5.0 boots to the end of the kernel log, then the screen goes blank Without this patch on the 835 laptops the user sees grub and then nothing and is left sad; however, with this patch the user sees some form of kernel life on the laptops and is left hopeful - which leads them to start looking around for fixes and help with the solution. Additional patches will need to be backported but without this patch it's a non-starter until 5.1 or after. If there is little to no regression risk as this adds a kernel parameter and this is required to enable these platforms to boot, if not other platforms, I would argue to include the patch for at least Disco if not Bionic since random people will attempt to boot the LTS release.
