APAR status

  • Closed as program error.

Error description

  • Timers with expiration set for 50 ms are firing after
    one sec with cpu folding enabled.
    

Local fix

Problem summary

  • Timers with 50ms timeout interval are getting triggered after
    1 sec/4 sec delay in rare case as cpu sleep is getting called
    even when  there are active timers on trb chain.
    

Problem conclusion

  • Fixed the code in such a way that cpu folding should not
    happen when there are active timers in their trb list.
    

Temporary fix
