RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
tuned-adm can timeout and tuned dies.

Version-Release number of selected component (if applicable):
tuned-2.3.0

How reproducible:
Sometimes

Steps to Reproduce:
1. Run the reproducer

Actual results:
dbus timeout

Expected results:
No timeout

Additional info:
Older tuned seems also affected.

Reproducer:

PROFILES=(balanced latency-performance powersave throughput-performance virtual-guest virtual-host)

for (( i=0; i < 100; i++ ))
do
  p=${PROFILES[$(( RANDOM % ${#PROFILES[@]} ))]}
  echo "iter: $i, profile: $p"
  tuned-adm profile $p
done

The source of this problem is currently unclear to me. I am working on it

I got it, there is race condition in the start/stop code. The race is there since the beginning of the tuned-2 development.

Simple reproducer:
tuned-adm profile balanced && tuned-adm profile balanced

Created attachment 821328 [details]
Proposed fix

I cannot reproduce this with tuned-2.3.0-3.el7.noarch either.
Marking as VERIFIED.
