[Bug 1971959] Re: [UBUNTU 22.04] dbginfo.sh: stabilization of data collection

[Frank Heimes]

Sorry, I totally missed to copy over the SRU Justification from my notes to the Bug description.
Did it now - test plan is included.

** Description changed:

+ SRU Justification:
+ ==================
+ 
+ [Impact]
+ 
+  * The s390x-specific dbginfo.sh script, used to collect runtime,
+    configuration and trace information for debugging Linux on IBM Z,
+    has stabilization issues while collecting data.
+ 
+  * Script hangups are possible on single commands,
+ 
+  * potentially missing data collection on error
+ 
+  * and overwrites of buffers by diag commands.
+ 
+ [Test Plan]
+ 
+  * Prepare an IBM zSystems or LinuxONE system
+    (ideally an LPAR as well as a z/VM guest)
+    with an Ubuntu 22.04 system.
+ 
+  * The s390-tools package is mandatory and always installed,
+    but needs to be replaced with an updated/fixed version - 
+    pick the version from the PPA that is mentioned below.
+ 
+  * Execute dbginfo.sh (as root or with sudo).
+ 
+  * Monitor the output and verify if all 18 steps are completed,
+    without any crashes or hangs.
+ 
+  * Inspect the size and content of the result file:
+    /tmp/DBGINFO-*.tgz
+ 
+ [Where problems could occur]
+ 
+  * The script might no run on older releases anymore
+    (but that's very unlikely).
+ 
+  * Some of the things that are gathered might not be
+    properly picked (like z/VM data on LPAR).
