During my test, it hangs in below 2 scenarios: 1) remove sb_edac driver, and then inject error, hang right now! 2) keep sb_edac drivr, inject error until storm happens (I changed the condition from 1 HZ to 1 minute to make it easy to trigger storm), after 5 errors are injected, codes enter *storm* mode, but hang right now again! At least, scenario 2 has direct connection with new patches. I need time to investigate because no any output after hang.
