They use the RTC interrupt for timing instead AFAIK so a broken interrupt 0 won't affect them. That's probably why we have so many problems with interrupt 0 on cheap systems. I tried it once to use in Linux too BTW, but it unfortunately cannot generate any of the standard Linux timer frequencies. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
