Public bug reported:
== Reported by <vanessa.ba...@ibm.com> ==
---Problem Description---
Good day, we recently installed Ubuntu 24.04 on a z LPAR.
After we run any test we usually collect the debug information in case we need
it, and what happened is that each time "sosreport" is run on the server
the system crashes and produces a dump.
I'll attach the full output when the "sosreport" command was run, but this is a
snippet of the last lines captured before it went down:
[plugin:zvm] skipped command 'vmcp ind sp': required kmods missing: vmcp,
cpint.
[plugin:zvm] skipped command 'vmcp ind user': required kmods missing: vmcp,
cpint.
Running plugins. Please wait ...
