--- Comment #87 from Mike Karels <karels@freebsd.org> ---
Yes, I loaded dtraceall.

Derived from the command you sent, and copying/pasting the function name:

pughole# dtrace -l | grep -i acpiexpci
30153        fbt            kernel          AcpiExPciBarSpaceHandler entry
30154        fbt            kernel          AcpiExPciBarSpaceHandler return
30155        fbt            kernel       AcpiExPciConfigSpaceHandler entry
30156        fbt            kernel       AcpiExPciConfigSpaceHandler return
30418        fbt            kernel              AcpiExPciClsToString entry
30419        fbt            kernel              AcpiExPciClsToString return
pughole# ./dtrace.d AcpiExPciConfigSpaceHandler
dtrace: failed to compile script ./dtrace.d: line 3: probe description

pughole# cat dtrace.d
