The bug was added in the patches for the 3.5 feature window. As you can see from the patch I made a mistake. During development I switched from passing a struct to the size of the struct, but left the sizeof. This results in us allocating 4 bytes (sizeof(int)) but then calling pci_free_consistent with the size of the struct.
