Description Matthew Tolentino 2002-04-22 11:39:44 EDT
Description of Problem:  There is an error in PCI fixup routine which is to be 
executed as a post kernel PCI enumeration by the PCI bus driver. That fixup 
routine is supposed to override IOSAPIC configurations with platform specific 
PCI configuration information. The error was introduced in to the kernel late 
last year that does not program IOSAPIC RTEs per the PCI fixup information in 
some cases. I will also attach a patch for this that addresses this issue.

Version-Release number of selected component (if applicable):
Redhat 7.2 kernels: 2.4.9-18, 2.4.9-21, 2.4.9-31

How Reproducible:

Steps to Reproduce:

Actual Results:
Unable to boot.  During boot process, addr 0x20 is dereferenced and IP is in 
firmware code

Expected Results:
RTEs correctly programmed and able to boot.

As discussed on the call, please file a minimal diff, thanks!
Comment 3 Michael K. Johnson 2002-05-14 15:37:19 EDT
Never mind, we did the legwork.

+-static int
+ iosapic_irq_to_vector (int irq)
seems unnecessary.  If a patch modifies only one file, there should
not be a reason to remove "static".
Comment 4 Bugzilla owner 2004-09-30 11:39:31 EDT
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
