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.

Customer says:
"With nouveau.modeset=0 screen comes back to life after blanking."

Comment 10 Benjamin Tissoires 2018-09-13 12:49:56 UTC
Apologies for the inconvenience. We won't be able to make 7.6 GA with this bug.
Moving to 7.7.

Comment 29 Rob Clark 2019-03-14 14:39:38 UTC
Should be resolved as of kernel-3.10.0-1020.el7 (at least w/ nouveau.runpm=0, which is a different bug)

Customer comment below:

Tested with P52 the RHEL-7.7-20190502.1-Workstation-x86_64-dvd1.iso snapshot (kernel-3.10.0-1040.el7.x86_64.rpm).

Closing the lid, machine suspends after 20 seconds.  I tried a sudo suspend hibernate, on resume screen did hang.

So the suspend works now? From your last comment it is not clear to me whether the resume works (in case it was suspend - to RAM) works as well or it does not only when resuming from hibernation.

Thanks
