Kernel panic found #4

I've managed to get the driver to crash. It was at a fairly random point, while using REAPER. There was a drum track and a bass track, going out to the same synth module, the drum track was on channel 10, and the bass on channel 1.

I'm going to try running REAPER in a VM because this way I can capture the output of the kernel panic, via a virtual serial port, and get some sort of stack trace.

oops.

only one output used without much traffic i guess. Is it reproducable with the reaper-project? Your 128 was used?

I will look, if i get a clue what happend ;-)

I am going to leave this issue open since I never figured out how to get it to crash again, but have not confirmed that it is stable either. Just in case anyone finds a crash, the way you would debug it is you would enable serial console in GRUB and capture the output with another computer's serial port (any old computer would work). I think it's better to have a hardware serial port instead of an USB adapter, I've only tried with a hardware port. Some modern motherboards (such as my MSI) still have a serial port header.

I have stopped using the MOTU with Linux, I setup a windows machine for music editing so I am no longer testing this module.
