Okay, I just tried it on my x86_64 RHEL5 Beta machine
(2.6.18-1.2714.el5) ..

# stap iostp.stp
semantic error: probe point mismatch at position 1 (alternatives: end
submit)
while: resolving probe point ioblock.request
semantic error: libdwfl failure (dwfl_linux_kernel_report_kernel): No
such file or directory
Ensure kernel debuginfo is installed
while: resolving probe point kernel.function("bio_endio")
semantic error: no match for probe point
while: resolving probe point ioblock.end
Pass 2: analysis failed.  Try again with more '-v' (verbose) options.
