Older FPGAs would sort of "ack" on register read, but this doesn't necessarily agree with how Linux expects IRQs. This results in some IRQs being dropped, and some IRQ X and nobody cared messages. Newer FPGA releases include a new ack enable bit, which changes the behavior and the IRQ will then use a normal ACK.
