I'm getting these on my Dell Latitude D830:

In some cases, there are several cmd/res lines listed. It's
happening about once an hour or so (not correlated with any other
event that I can see). It doesn't seem to be affecting operation of
the machine, but it's making me nervous.
Can anyone set my mind at rest? (Or suggest a fix?)
