Essentially when I place the network under heavy load (by writing data to a Ceph filesystem backed by 3xOSDs), I experience kernel crashes. I've harvested a few backtraces from the serial port and will paste them below as separate comments. I think the problem lies in the xgene driver, but I don't know enough to resolve where this problem is happening.
