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.

Comment 2 Yuki Okada 2019-12-05 01:49:24 UTC 
Similar issue is reported in the following environment.

kernel-4.18.0-147.0.3.el8_1.x86_64        
xorg-x11-drv-nouveau-1.0.15-4.el8.1.x86_64

NVIDIA Corporation GP107GL [Quadro P1000]
Comment 5 Yuki Okada 2019-12-09 02:20:34 UTC 
According to the customer, it is easier to reproduce if the machine is connected to an external monitor via USB type C to HDMI cable.
Comment 8 Yuki Okada 2019-12-25 03:31:17 UTC 
Similar issue happens in different call trace but the same RIP.

Comment 9 Yuki Okada 2020-02-27 09:56:19 UTC 
According to the customer, once this issue occured, an external monitor turns black and only a mouse cursor is displayed.

And it seems the nouveau warning sometimes occurs followed by a warning in vblank.

Hello, 
any update about the fix process on this bug ?
Comment 13 Lili Huang 2023-01-13 01:33:13 UTC 
Hello,
Customer closed the case because this issue doesn't happen again and he does not know how to reproduce the issue on purpose neither.
Comment 15 Steve Barcomb 2023-02-02 21:33:09 UTC 
All three attached cases are closed with the only customer we can see actually hitting this warning, no longer able to trigger the warning.  Please reach out to me directly if there is renewed interest in this bug.
