Currently, when an underrun occurs, a reset request is sent to the histogram hardware. This has been observed to cause a hang in the histogram collection cycle. The fix for this hang is to instead rely on the existing checks for histogram validity in the histgram read worker. When the underrun occurs, the histogram is invalidated, which in turn causes the histogram read worker to reset the histogram collection when it attempts to read its contents.
