bde 96/11/06 19:05:29 Modified: sys/i386/isa vector.s Log: Don't switch from fast interrupt handlers to normal interrupt handlers if interrupts are nested more than a few (3) deep. This only reduces the maximum nesting level by 1 with the standard drivers unless there is a related bug somewhere, but can't hurt much (the worst case is returning to hoggish interrupt handler like wdintr(), but such interrupt handlers hurt anyway). Fixed a previously harmless race incrementing the interrupt nesting level. This should be in 2.1.6 and 2.2. Revision Changes Path 1.23 +8 -4 src/sys/i386/isa/vector.s
