Description of problem:
After update to one of the recent kernels I started to get this in the boot log:

Version-Release number of selected component (if applicable):
kernel-2.6.27.5-37.fc9.i686
kernel-2.6.27.5-41.fc9.i686
not sure, but may be even kernel-2.6.26.6-79.fc9.i686

How reproducible:
always

Steps to Reproduce:
1. reboot.
2. observe the kerneloops message
3. grep the logs
  
Actual results:
kerneloops, suspend does not work

Expected results:
normal operation with working suspend.

Additional info:
Seems that this bug is observed not only in Fedora 9, but also in other releases. See https://bugzilla.redhat.com/show_bug.cgi?id=465657
Comment 1 Matthew Garrett 2008-12-09 20:33:40 UTC 
Can you attach the output of

ls -lR /sys/bus/pci/slots

and the output of the acpidump command from the pmtools package?
Comment 2 Chuck Ebbert 2008-12-09 21:01:36 UTC 
kernel 2.6.27.8 has 15 backported patches that are supposed to solve this problem.
Comment 3 Lev Shamardin 2008-12-09 21:05:47 UTC 
Unfortunately that particular system had a big file system corruption by an accident, so it was reinstalled to Fedora 10 and the problem disappeared (kernel 2.6.27.5-117.fc10).

Good news is that I possess another system which still shows this bug but with a non-stock kernel. It is an older Fedora 8 system running on a rebuilt kernel 2.6.27.6-43.fc9. The only difference from the stock .fc9 kernel is that "kernel_variant_posttrans" part is removed from the spec for the kernel to work on fc8 system. 

The original report was made on this system: http://www.smolts.org/client/show/pub_d33f4595-a01e-49c9-9ba8-e363b8ffccfa

I observe the simlar problem on this system: http://www.smolts.org/client/show/pub_07aa6c6b-657d-4ddc-b323-fe44a29d1a41
However it does not break suspend in this case.

I will attach dmesg output, ls -lR and acpidump to this bug.
