Based on the snippet of code you sent the following is true.
If ibit_mask changes => a packet was received && the packet data !=
ibit_mask
Do you really know that you are receiving a packet?
You might want to invest in a JTAG device so you can actually debug this
kind of thing.
Debugging this stuff by inspection is a royale pain.
