The safe thing to do is disable the timer after the DSP has completed the dump. During the dump processing, the DSP will clear the timer interrupt. I don't know what would happen if the timer were disabled prior to that.

The question is: can we disable the timer _before_ the DSP has finished dumping the stack? -- Felipe Contreras -- 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
