The test systemtap.stress/current.stp fails to build on ia64 machine with 2.6.22-rc2 because it takes too long to build. Notice that pass 2 takes 58 seconds of real time. $ /home/wcohen/stap_snap_200705231431/install/bin/stap -gv /home/wcohen/stap_snap_200705231431/src/testsuite/systemtap.stress/current.stp Pass 1: parsed user script and 53 library script(s) in 1920usr/24sys/2332real ms.

This is no longer a problem on ia64. On the RHEL 5.4 the nightly build results show this tests now passing.
