Problem using bulk mode (relayfs)


I am having trouble running stap in bulk mode on a script that otherwise 
works fine.  That is, I normally run with just "-g" but with "-g -b" it no 
longer works.  Here's the output with one -v.   Is this a known problem? 

OS version: 2.6.16 modified with various real-time patches
stap version:   (version 0.5.13 built 2007-02-12)    (Using Red Hat 
elfutils 0.125 libraries.)

Pass 1: parsed user script and 54 library script(s) in 260usr/0sys/269real 
ms.
Pass 2: analyzed script: 6 probe(s), 14 function(s), 3 embed(s), 0 
global(s) in 300usr/60sys/356real ms.
Pass 3: using cached 
/gsa/watgsa/home/p/e/perryche/.systemtap/cache/4a/stap_4aca05003686bb4d8c3530e87c8a2d4d_11456.c
Pass 4: using cached 
/gsa/watgsa/home/p/e/perryche/.systemtap/cache/4a/stap_4aca05003686bb4d8c3530e87c8a2d4d_11456.ko
Pass 5: starting run.
insmod: error inserting 
'/tmp/stapUcDLAt/stap_4aca05003686bb4d8c3530e87c8a2d4d_11456.ko': -1 
Unknown symbol in module
ERROR, couldn't insmod probe module 
/tmp/stapUcDLAt/stap_4aca05003686bb4d8c3530e87c8a2d4d_11456.ko
Pass 5: run completed in 0usr/10sys/30real ms.
Pass 5: run failed.  Try again with more '-v' (verbose) options.

Increasing the level of verbosity generates no error/warnings in Passes 
1-4 and no additional output in the failing Pass 5.
