I've tried your code again, replacing src/sys/arch/i386 with contents of
both i386intr4.tgz and i386intr5.tgz on the same machine.

Here is the result;

  kernel                              status
  ------------------------------------------
  i386intr4
    a. GENERIC				OK
    b. GENERIC_MPVERBOSE		NG
  i386intr5
    c. GENERIC				OK
    d. GENERIC_MPVERBOSE		OK

The kernel built from GENERIC_MPVERBOSE (i386intr4) stops the same place,
and warns "Timedout SCB handled by another timeout" again and again.
However, the kernel built from GENERIC_MPVERBOSE (i386intr5) works. :-)
See end of this mail for dmesg output of (b) and diff from (b) to (d), please.

Thanks!
