scsi.stp won't run


Hi,

I'd like to try the kernel event trace tool
(http://sourceware.org/ml/systemtap/2005-q4/msg00458.html).
When running "stap -vg -I . sample.stp" I get the following
error, and similar errors for other scsi probes:

parsed 'scsi_io_completion' -> func 'scsi_io_completion'
pattern 'scsi_mod' matches module 'scsi_mod'
focused on module 'scsi_mod' = [f8857000-f8878169, bias 0]
semantic error: cannot find module scsi_mod debuginfo: Unsupported relocation type
semantic error: no match for probe point
while: resolving probe point module("scsi_mod").function("scsi_io_completion")
semantic error: no match for probe point
while: resolving probe point addevent.scsi.iocompleted
semantic error: no match for probe point
while: resolving probe point addevent.scsi


Parsing of other *.stp files seems to okay.

I have verfied that stap is working by running other simple sample probes successfully. kernel-debuginfo is installed and does provide
/usr/lib/debug/lib/modules/2.6.14-1.1653_FC4/kernel/drivers/scsi/scsi_mod.ko.debug
scsi_mod has been loaded as a module.

SystemTap translator/driver (version 0.5.2 built 2005-12-19)

Do you have got any idea what is going wrong?
Thank you.

Martin
