Hey Steve, I saw something similar while testing 2.6.32, by chance are you using any power management patches? I had to disable CONFIG_CPU_IDLE: -CONFIG_CPU_IDLE=y -CONFIG_CPU_IDLE_GOV_LADDER=y -CONFIG_CPU_IDLE_GOV_MENU=y +# CONFIG_CPU_IDLE is not set Regards, -- Robert Nelson http://www.rcn-ee.com/ -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
