kvmarm tags kvm-arm-for-4.2, 4.3, and v4.4-rc6 does not boot on Mustang
Hi,
I have been trying to test one of the recent tags in kvmarm git tree, kvm-arm-for-4.2, 4.3, and v4.4-rc6 on Mustang, but none of them seem to enter the linux boot process. Has anyone verified any of these work on Mustang? If so can I have a working .config to continue testing?

Just use mainline tags instead of the kvm-arm-specific ones.
Any recent kernel, like v4.3 or v4.4-rc6 boots just fine on my Mustang with defconfig.

Hi Christoffer,
I don't see those mainline tags you mentioned in the tree.

I don't think we push mainline tags to the kvmarm tree; you can fetch those directly from Linus' tree.

Hi Christoffer,
After some investigations, it seems newer kernels does not boot on the Mustang board which I have access (in the Linaro Server Lab).
I am using the Fedora 23 userland, 4.2.x Fedora kernels do boot, but 4.4.x Fedora kernels do not (they are downloaded from the Koji site or own-built ones using fedpkg). I am not sure at this moment, the F/W is too old or not.

I don't know anything about distro kernels, I only follow mainline and just booted mainline just fine on my mustang.

Does your Mustang boot via UEFI? Mine does. Mainline v4.4-rc6ish seems to have an issue with libstub.

No, I use u-boot.
Sorry I can't be of any help then.

Using newer F/W, I was just able to boot a 4.4.0 kernel with KVM.
