Why can't probe do_page_fault?

[Frank Ch. Eigler]

Hi -

do_page_fault is marked "__kprobes" in many kernel versions,
precluding kprobes from being placed there at run time.  The
translator knows this and prevents even the attempt.

You'll need to give more specifics about your kernel version, exact
error messages, etc.  See the "HowToReportBugs" wiki page.
