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@s8330031:~# echo $?
2
and in LPAR:

4 of 8: Collecting sysfs

6 of 8: Collecting config files
root@s83lp31:~# echo $?
2
Most likely this is caused by the implementaion of sh (symlinked to dash)
root@s8330031:~# ll /bin/sh
lrwxrwxrwx 1 root root 4 Feb 17 21:25 /bin/sh -> dash*
root@s8330031:~# rm /bin/sh
root@s8330031:~# ln -s /bin/bash /bin/sh
root@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

# 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.
