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:
Under KDE if you choose to shutdown or reboot the system seems to lag a bit when logging the user out and there is a stuttering and slowing of the logout audio chime. 

Version-Release number of selected component (if applicable):
kdebase-4.3.4-4.el6.x86_6

How reproducible:
Every time.

Steps to Reproduce:
1. Log into KDE as a normal user
2. Choose to either shutdown or reboot
3.
  
Actual results:
The user logout process seems pretty laggy and there's audio stuttering and slowness to the audio chime.

Expected results:
The logout process (killing of processes) should not be Windows-like in speed and audio should not become garbled.

Additional info:

inclusion in the current release of Red Hat Enterprise Linux.

Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
