Kernel PCI Scan Bug - No feedback 8 days after bug submittal

[Charles Butterfield]

I've had what seems like a fairly serious kernel bug related to PCI
scanning open for over a week, with no hint that anybody has read it,
triaged it, etc.  Some feedback would sure be nice.  I'm posting this on
the email list, since I'm not really sure how else to get developers to
notice the formal bug report.


History


Nov 3 -- I reported a problem with Xorg not finding my video card on
this email list(subject "FC6 - X server can't start - embedded ATI Rage
XL AGP - Dell PowerEdge 700").  Got a few posted responses (thanks!).


Nov 5 -- Submitted bug report
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=214050 .


Nov 6 -- After further debugging, I realized the problem is a kernel
problem.  I changed the title and component to indicate such.


Nov 14 -- So far, no response of any sort to the submitted bug #214050.
Still classified as NEW, no indication that anyone is doing anything,
such as notifying the upstream folks, etc. (I started to notify the
upstream kernel folks myself, but stopped when I read the notice to not
submit bug reports that came from an existing distro).


Problem Summary:

In the kernel used by FC6, there is a PCI scan/enumeration bug that
manifests itself on some machines (like mine) as a mismatch between the
contents of /proc/bus/pci/devices (e.g. 14 devices) and the nodes in
/proc/bus/pci/xx/* (e.g. 15 devices).  Clearly this could cause numerous
problems.  In my case it causes Xorg to fail to find my video card.
YMMV
 
This problem did not exist in the kernels used by FC5 (or at least did
not manifest on my system).
