  both under z/VM:

  dbginfo.sh: Debug information script version 1.33.0-build-20160209
  Copyright IBM Corp. 2002, 2015

  Hardware platform     = s390x
  Kernel version        = 4.4.0 (4.4.0-6-generic)
  Runtime environment   = z/VM

  1 of 8: Collecting command output

  2 of 8: Collecting z/VM command output

  3 of 8: Collecting procfs

  4 of 8: Collecting sysfs

  5 of 8: Collecting log files

  6 of 8: Collecting config files

  root at s8330031:~# echo $?
  2

  and in LPAR:
  root at s83lp31:~# dbginfo.sh 
  dbginfo.sh: Debug information script version 1.33.0-build-20160209
  Copyright IBM Corp. 2002, 2015

  Hardware platform     = s390x
  Kernel version        = 4.4.0 (4.4.0-6-generic)
  Runtime environment   = LPAR

  1 of 8: Collecting command output

  2 of 8: Collecting z/VM command output skipped - no z/VM environment

  3 of 8: Collecting procfs

  4 of 8: Collecting sysfs

  5 of 8: Collecting log files

  6 of 8: Collecting config files

  root at s83lp31:~# echo $?
  2

  Most likely this is caused by the implementaion of sh (symlinked to dash)

  root at s8330031:~# ll /bin/sh
  lrwxrwxrwx 1 root root 4 Feb 17 21:25 /bin/sh -> dash*
  root at s8330031:~# rm /bin/sh
  root at s8330031:~# ln -s /bin/bash /bin/sh
  root at s8330031:~# ll /bin/sh
  lrwxrwxrwx 1 root root 9 Feb 20 18:11 /bin/sh -> /bin/bash*

  after I symlinked sh to bash, it worked.

  @IBM, looks like we need some adjustments in dbginfo.sh to make it posix compliant and compliant to Ubuntu's dash.
  For me it looks like the problem is in this line here:
      local network_devices=[[:space:]]\+/\1/g')

  Hi Thorsten,

  could enable  shell tracing for the dbginfo.sh.  That means, add an
  "set -x" in the beginning of the script.  Also please use the
  /bin/dash for reproduction.  Please attach the generated trace output
  (2>trace.log).

  Thanks.

  Problem occurs only, if there is more than one network interface!!

  I already attached the trace.log

  root at s83lp31:~# cat /tmp/DBGINFO-2016-02-22-16-55-19-s83lp31-21EC87/osa_oat
  cat: /tmp/DBGINFO-2016-02-22-16-55-19-s83lp31-21EC87/osa_oat: No such file or directory
  root at s83lp31:~# dash
  # network_devices=[[:space:]]\+/\1/g')
  # echo $network_devices 
  hsccw0.0.8300 enccw0.0.e300 enccw0.0.f500
  # which qethqoat
  # 
  and here I expected the dbginfo.sh to jump to line 683:
  pr_syslog_stdout "7 of ${COLLECTION_COUNT}: Collecting osa oat output skipped - not available"

  which obviously does not happen...

  I'll dig into that and continue analysing.
