Yes, this the way to do.
Please patch lpae, default and vanilla to be consistent across configs.
The patched kernel reached Factory/Tumbleweed but there is still a black screen! :(
Are you sure it is included? I see 4.1.5 version in http://download.opensuse.org/ports/armv7hl/factory/repo/oss/suse/armv7hl/ And my patch was applied to Kernel:stable after 4.1.6 patch.
Yes, I can see: kernel-lpae-4.1.6-2.1.armv7hl.rpm in this repo and in the build log of JeOS-chromebook image, it is the same version. Guillaume
The boot (and reboot) problem is fixed with latest image.

I can send patch to opensuse-kernel ml if thats suitable, this way is described on the wiki
https://en.opensuse.org/openSUSE:Kernel_git#Submitting_your_changes_to_the_k... What do you think is patch for lpae enough or better add default and vanilla also? --- Best Regards, Misha Komarovskiy zombahatgmaildotcom

Thanks.
Could you submit your patch to stable branch for default, lpae and vanilla flavours, please?
Patches against master branch should follow once git repo fixed.
