I hit a glitch in os-prober which under some conditions takes files /boot/vmlinux-XXX.gz as kernels and generates menu entries for them. What are these files for? I wonder how I can reliably skip the without breaking some valid case. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] [PATCH] config: armv7hl: Compile KGDB serial console into kernel
by Matwey V. Kornilov 02 Oct '14

02 Oct '14

From: "Matwey V. Kornilov" <matwey.kornilov(a)gmail.com> A serial console is the major communication for ARM devices.
