Created attachment 319881 [details] boot messages Description of problem: X fails to start, becuase there is no /dev/agpgart. There certainly was one in 5.2. i965.

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.

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.

in kernel-2.6.18-120.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5
