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 Vladimir Benes 2011-03-14 15:20:06 UTC 
Description of problem:
I can see Lenovo T410 X server lock ups (again) we fine tuned it in 6.0 but now it's there again and it's very occasional. Waiting for better backtrace than I have now. 

Version-Release number of selected component (if applicable):
xorg-x11-drv-nouveau-0.0.16-9.20110107gitb795ca6.el6.i686
kernel-2.6.32-119.el6.i686

How reproducible:
occasionally

Steps to Reproduce:
1.use firefox/evince/thunderbird maybe some flash

Actual results:
sometimes X server freezes

Expected results:
no freezes due to X server... NEVER!

unusable backtrace ..

pasting it here just in case you can see anything in it.. waiting for another lockup with debuginfos installed
Comment 2 Ben Skeggs 2011-03-15 00:55:11 UTC 
Yes, this is due to another lost patch during the rebase.  Upstream does not disable acceleration for these chipsets even though there is the know random-hang on them.

Comment 11 Vladimir Benes 2011-04-11 15:21:21 UTC 
I am seeing huge performance regression after resume from suspend. Can we track it here or should I open separate bug report?

I'd open a separate report.

I do believe this is probably what you're experiencing: http://www.nvnews.net/vbulletin/showthread.php?t=158091&highlight=3100m

I have no clue why people are blaming the video driver, but, anyways...
