As mentioned in #266 there where random hangups using the I2C peripheral. Moving the DMA enable sequence back into the init code and re-adding the spurious bus error detection code from stmf4 error fixed these. I didn't verified what change fixed the issue but my guess would be that enabling the DMA request from an IRQ context and just before starting a transfer isn't the best idea.
