This is due to a serious bug in both Etherboot and gPXE (at least until very recent ones) where they leave interrupts disabled after INT 1Ah and INT 15h. I have pushed out a -pre9 which works around this problem, plus added an STI to reset_idle which should hopefully avoid the worst instances of the same class of problems. I now also dump an error and debugging message if interrupts are ever off at do_idle time. -hpa -- H. Peter Anvin, Intel Open Source Technology Center I work for Intel.
