Hi,

Has anyone tried undefining PEND_INTS to fix this yet?

We REALLY need to determine if this is being caused by the SMP code!
Another thing I see that is a possible leak is in apic_vector.s:

*** apic_vector.s.orig	1997/07/30 22:46:49	1.18
--- apic_vector.s	1997/08/09 05:55:31
***************
*** 45,50 ****
--- 45,51 ----
  	orl	$IOART_INTMASK,%eax ;		/* set the mask */	\
  	movl	%eax,IOAPIC_WINDOW(%ecx) ;	/* new value */		\
  7: ;									\
+ 	lock ;								\
  	orl	$IRQ_BIT(irq_num), _ipending ;	/* set _ipending bit */	\
  	IMASK_UNLOCK ;				/* exit critical reg */	\
  	movl	$0, lapic_eoi ;			/* do the EOI */	\
