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.
Pei,
More questions:
o Do you have any VMs running at all? Or the real-time host profile applied?
o How similar is this to bug 1817045 ?
o Since your system is a skylake, make sure you have microcode version
0x2000064

Luiz,
No, just installing a RT host will cause this issue. No VMs is running, no real-time host profile applied.

They are different. There is no VM with this bug.

Currently this system is installing 8.2-rt. The microcode:
[root@hpe-dl380gen10-01 ~]# dmesg | grep microcode
[ 0.000000] microcode: microcode updated early to revision 0x2006906, date = 2020-04-24
[ 11.127493] microcode: sig=0x50654, pf=0x80, revision=0x2006906
[ 11.131307] microcode: Microcode Update Driver: v2.2.
Best regards,
Pei
Verified with 4.18.0-233.rt7.45.el8.x86_64:
RT host works very well on UEFI server, the hang issue cannot be reproduced any more.
So this issue has been fixed very well. Move to Verified.
