I followed the Acer Chromebook R13 guide for my Lenovo S330 which has the same SoC and board (hana.)
The problem is that sbs_battery appears to be non functional and floods the kernel logs about it reading more than 32 bytes, subsequently flooding all vts as well until I set kernel.printk; While this works it's less than ideal and still spams the log in the background making it hard to debug other things in the future. I first tried modprobe -r sbs_battery but the module appears to be builtin with the provided kernel image (3.18.0-12-ARCH) and I know next to nothing about the kernel image format (it looks like garbage as far as the few tools I tried can tell) nor the firmware on this chromebook. I'd appreciate any suggestions, thanks!
