There's a similar report in Debian. I've started a scratch kernel with the debug patch applied from there. Could you please install it and attached the kernel output when the build completes?

1) That isn't the right kernel. You need the kernel with the debug patch, which is the one pointed to by the URL in comment #2 and is still building.
2) We need the output of dmesg or the oops output on boot, not the RPM output.
Understood, will wait and look for that kernel..

Ok, i installed kernel-debug-188.8.131.52-5.1.fc15.x86_64.rpm. The oops are the same as in https://bugzilla.redhat.com/show_bug.cgi?id=735437#c0. I can not boot up also this kernel. The picture attached shows the last state were the kernel is hanging.
There should be a line printed out that looks like:
"connecting <something> to <something>
before the kernel oops output similar to what you captured in the picture in comment #1. Can you tell us what that says?

Sorry, i cannot find this line. Here are the pictures..

If you add ignore_loglevel to the kernel command line, does that line show up?
connecting (null)(0):0(/0) to Extension 7(0):0(/2)

proposing as NTH.
This build has a patch from upstream that is expected to fix the issue. When the build completes, could you please test it out and let us know if it works?
kernel-debug-184.108.40.206-5.2.fc15.x86_64.rpm is working for me.

Thank you very much for the debug and test effort. I've committed the fix to the fedora repository and it will be included in the next official build for f15, f16, and rawhide.
I thank You!
Josh, could do you a new F16 build + update fairly soon, so we can make sure to pull this into Beta? Thanks!

There's a PCI regression/bug being worked on upstream. A user has indicated that it's causing 734201 for him. I'm waiting for a fix to materialize there before I do another build. Hopefully later today/tomorrow.
Confirmed to work with Asus N43S (bug 734963). Thanks.
kernel-3.1.0-0.rc5.git0.0.fc16 has been submitted as an update for Fedora 16.
Discussed at 2011-09-09 blocker review meeting. Accepted as Beta NTH as this causes affected systems not to boot, which obviously can't be fixed post-release.
* should fix your issue,
* was pushed to the Fedora 16 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing kernel-3.1.0-0.rc5.git0.0.fc16'
as soon as you are able to, then reboot.
