  ISST-LTE: Ubuntu 14.04.4 LPAR interrupts at check_and_cede_processor

Status in linux package in Ubuntu:
  Fix Released

  == Comment: #0 - YUECHANG E. MEI  - 2015-12-11 17:19:07 ==
  ---Problem Description---
  We have an Ubuntu 14.04.4 LPAR, conelp2. It is running stress test: base, io, 
and tcp. When checking "dmesg", we see this interruption: 

  [Fri Dec 11 13:58:50 2015] --- interrupt: 501 at plpar_hcall_norets+0x1c/0x28
  [Fri Dec 11 13:58:50 2015] LR = check_and_cede_processor+0x34/0x50

  In the previous test, conelp2 stopped all the stress tests by itself
  because it ran out of memory. Is the out of memory issue relating to
  the interruption?

  ---uname output---
  Linux conelp2 4.2.0-21-generic #25~14.04.1-Ubuntu SMP Thu Dec 3 13:55:42 UTC 
2015 ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = EUH Alpine 8408-E8E 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
   1. install Ubuntu 14.04.4 in a LPAR, then update to the latest 14.04.4 
kernel by using this workaround:
  echo "deb http://software.linux.ibm.com/pub/ubuntu-ppc64el-repository/ 
trusty-proposed main restricted universe multiverse" >> /etc/apt/sources.list

  apt-get update

  apt-get install linux-image-generic-lts-wily

  2. Setup the Stress test, and start base,io, tcp
  3. After an hour, check dmesg, then you will see the message about the 
interruption 
   
  Stack trace output:
   no
   
  Oops output:
   no
   
  System Dump Info:
The system is not configured to capture a system dump.
   
  *Additional Instructions for Yuechang (Erin) Mei /ye...@us.ibm.com,  Raja

  -Post a private note with access information to the machine that the bug is 
occuring on.

  ISST-LTE: Ubuntu 14.04.4 LPAR interrupts at check_and_cede_processor

Status in linux package in Ubuntu:

  ---Problem Description---
  We have an Ubuntu 14.04.4 LPAR, conelp2. It is running stress test: base, io, 
and tcp. When checking "dmesg", we see this interruption: 

  [Fri Dec 11 13:58:50 2015] --- interrupt: 501 at plpar_hcall_norets+0x1c/0x28
  [Fri Dec 11 13:58:50 2015] LR = check_and_cede_processor+0x34/0x50

  In the previous test, conelp2 stopped all the stress tests by itself
  because it ran out of memory. Is the out of memory issue relating to
  the interruption?

  ---uname output---
  Linux conelp2 4.2.0-21-generic #25~14.04.1-Ubuntu SMP Thu Dec 3 13:55:42 UTC 
2015 ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = EUH Alpine 8408-E8E 
   
  ---Debugger---
  A debugger is not configured
   
  ---Steps to Reproduce---
   1. install Ubuntu 14.04.4 in a LPAR, then update to the latest 14.04.4 
kernel by using this workaround:
  echo "deb http://software.linux.ibm.com/pub/ubuntu-ppc64el-repository/ 
trusty-proposed main restricted universe multiverse" >> /etc/apt/sources.list

  apt-get update

  apt-get install linux-image-generic-lts-wily

  2. Setup the Stress test, and start base,io, tcp
  3. After an hour, check dmesg, then you will see the message about the 
interruption 
   
  Stack trace output:
   no
   
  Oops output:
   no
   
  System Dump Info:
The system is not configured to capture a system dump.
   
  *Additional Instructions for Yuechang (Erin) Mei /ye...@us.ibm.com,  Raja  
Sunkari /rajas...@in.ibm.com: 
  -Post a private note with access information to the machine that the bug is 
occuring on. 
  -Attach sysctl -a output output to the bug.
