Summary 08347: vf2o, overrev, sgt24h: "Fatal error: I960: 2f2f2f2e: Unhandled 00" during Self-Test of CPU working RAM
Description During Self-Test of CPU working RAM, i960 CPU seems jump to some random address, causing either Crash(overrev/sgt24h/(sometimes)vf2o), or Failure of RAM test(all vf2 revisions).

Occasionally, vf2x CAN pass its CPU RAM test.

Did some study in debug mode: seems when the ram-test code writing to i960 Interrupt Table area, an unexpected INT happens.
Steps To Reproduce When demo (means all inits should have been done), press F2 to enter self-test, then select memory test.
