I could not see the entire page. Normally on this level, the af.xxx file will
contain 1) the page that it had read followed by 2) a physical re-read of the
same page from disk. I would be interested in seeing what that contained. Was
it the same page? What does the page on disk actually look like? This can be
gotten from oncheck -pP 0x5c 0x48deb. Is there a case for this problem?
