What's the problem? Describe what went wrong.
Frequent invalid read errors at the end of Hunnigan calls, which freezes the game. Buzzing noise plays if the MMU is enabled. Dual
core is disabled and ISO dump verifies as good. The error message says: "Invalid read from 0xffffffe4, PC = 0x801959"

What steps will reproduce the problem?

Play until a Hunnigan call occurs and then ends. Occurs about half the time.

Enabling write-back cache seems to prevent the error.
