Description Sam Folk-Williams 2007-10-23 12:18:20 EDT
Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:

Always
Steps to Reproduce:
1. Run sysreport command with no options
2.
3.
  
Actual results:

Sysreport runs and echos "t" to /proc/sysrq-trigger

Expected results:

Sysrq-t should not be issued by default
Additional info:

This went in as a feature but it's really a regression. Issuing sysrq-t should
only be done in specific circumstances. It should not be done as a routine
practice when sysreport is normally run. Sysrq-t can cause a large variety of
problems including applicaiton failover, scsi resets/timeouts, bonding failover,
and application hangs.
