    Very strange!  Removing SMP and APIC_IO options from my config, the kernel
does not boot.  It shows some errors in IDE interrupts, and panics after lots
of errors while probing SCSI devices.  Very strange, since GENERIC works
without problems.

    Oh!  This remembers me!  The bug with ipfw and msgbuf also happens in
GENERIC -stable!

    I tried only removing DUMMYNET from config, and the bug continues.  Should
I try the changes below?
