Device not initialized

[Taylor Jones]

It appears that the FifoReadyQueue for each device may not actually be initialized. I am getting a segfault when a job is pushed onto a device queue. From the debugger it looks like the queue is pointing at garbage memory.

queue {Cannot access memory at address 0x40d5fbde00000000
