I've been sending only myself and Kevin the build reports from my own builder, but since there seems to be interest for this I'll include them on the kernel-build-reports list as well.
I build the following trees on a regular basis, i.e. polling for updates multiple times an hour:
arm-soc for-next mainline master linux-next master arm-soc to-build, which we use to get a build iteration out of before we push it to for-next sometimes "queue", which is linux-stable -rc queues, currently 3.9.y - 3.11.y.
I boot them on a selection of boards:
* Cubie * Cubie2 * Cubox * Panda ES (omap2plus_defconfig and multi_v7_defconfig) * Arndale * Atmel SAMA5 * Tegra3 Beaver (tegra_defconfig and multi_v7_defconfig) * STE Snowball (u8500_defconfig and multi_v7_defconfig [known broken])
More hardware will be added over time as I buy it (or receive it from generous hardware vendors). Beaglebone black and an A31 eval board from Allwinner still need to be added, for example. I also have a seemingly broken Wandboard Quad that I'll get replaced and added back in.
