Use the virt_to_bus & bus_to_virt functions rather than phys_to_bus & bus_to_phys, since the addresses accessed by the CPU will be virtual rather than physical. On MIPS physical & virtual addresses differ as we use virtual addresses in kseg0, and attempting to use physical addresses directly caused problems as they're in the user segment which would be mapped via the uninitialised TLB.
