Hi, Boris

Have you tested Thomas' patch. 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. (lockdep?)
