Subject: kernel panic with systemtap 0.5.4-0.EL4

This occured while probing the qla2xxx module on a 2.6.9-29.EL kernel (i686).

Kernel panic - not syncing: /usr/share/systemtap/runtime/transport/procfs.c:145: spin_lock(/usr/share/systemtap/runtime/transport/procfs.c:e05b4bb0) already locked by /usr/share/systemtap/runtime/transport/procfs.c/201
