I had to increase nitpicker to 32M to get this to work.  There are still a number of odd errors being produced but the demo is running.  It is worth noting, however, that the base demo runs fine with NOVA but does not with seL4 unless the memory is increased on nitpicker.  Here's my output if you are interested in analyzing it.

thank you for reporting. We haven't noticed this problem so far.

Those components are apparently starved for memory. Could you try
increasing the RAM quota of them?
