Game over. There is no PC technology that doesn't have some problems with time handling 8) > I thought about Geode (NS), but I found some info that it doesn't have > TSC, or it works not properly (the PPS needs TSC). > And of course has to work excellent with linux. The Geode aka Cyrix MediaGx TSC problems are not in the TSC but in the PIT emulation in the chipset. That problem isnt present on the 5530 and later chipsets. So its a long buried problem. You might also want to look at the VIA Eden based boards if its got to be embedded (fanless 550MHz) - 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/
