This appears to actually be an issue with the kernel, which I believe is the same as the kernel in the Android version of the device. Therefore, unless I'm missing something, the title is misleading - this is actually an issue with Mediatek's Linux kernel modifications, which applies to Android, Ubuntu, and anyone else who tries to make a Linux-based phone with Mediatek hardware using Mediatek's official kernel patches.
