    sys/i386/isa         ipl.s 
  Log:
  doreti and splz were improperly requiring that the MP lock be held in order
  to process delayed FAST interrupts.  This could result in clock interrupts
  getting delayed indefinitely when the MP lock was held by another cpu.
  The delayed clock interrupts further resulted in clock-related issues such
  as the system time running slow, and other problems.
