Description Clark Williams 2010-05-18 18:07:07 UTC 
Description of problem:
rtctl init script allows multiple simultaneous execution instances

Version-Release number of selected component (if applicable):
rtctl-1.7-1.el5rt.noarch

How reproducible:
always

Additional info:

rtctl is invoked via a udev rule which looks for the SYSFS{irq} attribute. After a suspend/resume or a modpobe -r /modprobe of a multi-irq device driver, multiple invocations of the rtctl service start script may be run.
Comment 1 Clark Williams 2010-05-18 18:08:07 UTC 
v1.8 of rtctl adds a lockfile to the service script to prevent more than one instance running at a time.
