The problem is with the periodic SMM interrupt and the bios. The attached program (ich-periodic-smm-disable.c) will fix the problem. For more information on what it does, see the Intel ICH3 datasheet. compile as 'gcc ich-periodic-smm-disable.c; ./a.out' and you will be good. Run this on each boot. I think you only need to clear PERIODIC_EN. --don
ich-periodic-smm-disable.c
