[Kernel-packages] [Bug 1661363] Re: Fails to load compressed kernels on arm64
As mentioned on IRC, we shouldn't include amd64 in this unless we know that it actually improves amd64 support. My guess is that this doesn't help x86 - IIRC, those images decompress themselves at runtime. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to kexec-tools in Ubuntu. https://bugs.launchpad.net/bugs/1661363 Title: Fails to load compressed kernels on arm64 Status in kexec-tools package in Ubuntu: In Progress Bug description: [Impact] kexec-tools will not load a compressed kernel on arm64.

The debian/control file lists gnu-efi and libz-dev only for ia64, since amd64, and arm64 (may be other archs) also need these dependencies for it to support compressed kernel we need something like the following change for it to work on those archs. -Build-Depends: debhelper (>= 7.0.0), dh-autoreconf, gnu-efi (>=3.0a-4)[ia64], libz-dev[ia64], po-debconf +Build-Depends: debhelper (>= 7.0.0), dh-autoreconf, gnu-efi (>=3.0a-4)[amd64 arm64 ia64], libz-dev[amd64 arm64 ia64], po-debconf I will upload a patch to zesty shortly. ** Changed in: kexec-tools (Ubuntu) Assignee: (unassigned) => Manoj Iyer (manjo) ** Changed in: kexec-tools (Ubuntu) Status: New => In Progress -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to kexec-tools in Ubuntu. https://bugs.launchpad.net/bugs/1661363 Title: Fails to load compressed kernels on arm64 Status in kexec-tools package in Ubuntu: In Progress Bug description: [Impact] kexec-tools will not load a compressed kernel on arm64.
