Why was the linter messed up?
...
There are a number of combo loops which need fixing outside the icache. They may be fixed in main.
We get to instruction address 50 now!

start speculative checking on CSR* satp, *
add some slight delays in some CSR checkings to make them deterministic
I realize this verilog is incredibly un-idiomatic. But I still don't
know of anything better. If you figure it out, please let me know
