Thanks for the response. I backported that patch to 2.6.23.8, but it didn't make a difference. I also went ahead and tested 2.6.24-rc3 (with no changes to the existing config settings): With the new CPU_IDLE option set to "n", it still hangs, but much less frequently than on 2.6.23.x. In 25 tries, there were 3 hangs, all after "input: AT Translated Set 2 keyboard as /class/input/input0". With CPU_IDLE set to "y", it didn't hang at all in 25 tries. However, CPU_IDLE=y produces these additional messages, which may explain why: Marking TSC unstable due to: TSC halts in idle. ... Time: acpi_pm clocksource has been installed. Not sure what else to try at this point... -- Jordan Russell - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
