Bill, what vendor and model is this on? P. Intel i965. Non-vendor box. This bugzilla has Keywords: Regression. Since no regressions are allowed between releases, it is also being proposed as a blocker for this release. Please resolve ASAP. Is it possible to attach a lspci output and a dmesg from both a working and non-working kernel on the affected hardware? A sysreport would be even better. Thanks. *** Bug 466898 has been marked as a duplicate of this bug. *** I'll add some debugging logs shortly, but just dup'd bug 466898 against this bug. We're fine up until -117.el5. A bunch of changes to support Cantiga/Eaglelake went into -118.el5 and I suspect that's related to these support problems on 965. I've verified this is a regression introduced in the -118.el5 kernel. I'm proposing as a beta blocker at least until we know the extent of the damage.

I'll also try to track down HW and build a kernel which puts this device back into the intel-agp.c code. P. Zhenyu, Can you help on this? Created attachment 320339 [details]
RHEL5 fix for this issue
This patch fixes the problem on Jay Turner's system.
airlied & mchehab,
Is there a reason this code was pulled from the driver? Is there something I am missing?
P.
I have one of the older Intel SDV boxes with: 00:02.0 VGA compatible controller: Intel Corporation 82G35 Express Integrated Graphics Controller and can confirm it is still working with the -119 kernel This patch is fine, I'm not sure how that got removed in Mauro's original backport. I even reviewed it and missed it. Please send to rhkernel-list asap and I will ACK it. Created attachment 320411 [details]
RHEL5 fix for this issue
in kernel-2.6.18-120.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2009-0225.html |
