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. YMMVThis problem did not exist in the kernels used by FC5 (or at least did not manifest on my system).Regards,-- Charlie B ----------------------------------- Charles Butterfield, Chief Engineer Fax: 443-285-0799 Web: www.nextcentury.com |
