Did you fix multiple simultaneous DMA transfers in this? And easy test is to start jack audio. Jack will start simultaneous cyclic transfers on both the ALSA input and output. Since cyclic transfers never end, multiple simultaneous transfers has to work. Last time I tried it I got an immediate GPF when the second cyclic transfer was started.
I didn't get a chance to test with jack yet, but I don't see any reason why two cyclic transfers wouldn't work, assuming they're on different vchans.
Were you by any chance booting off of NAND by the way? That caused a GPF because the bootloader left the hardware in a dirty state, but it should be fixed now.
