Description Matthew Wilcox 2004-02-04 19:12:00 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux ia64; en-US; rv:1.6)
Gecko/20040122 Debian/1.6-1

Description of problem:
The acpiphp driver assumes that all PCI devices have 6 BARs.
Bridges have only 3 BARs and you don't program them the same
way as you program normal PCI devices.  This leads to all kinds
of strange bits of bridge configuration space being treated as
if they were BARs and much pain ensues.

Version-Release number of selected component (if applicable):
kernel-2.4.21-9.EL


How reproducible:
Always

Steps to Reproduce:
1. Boot an rx4640
2. Attempt to insert a quad-port tulip card into a slot
3.

Actual Results:  Machine crashes

Expected Results:  Card should have been inserted

Additional info:

I intend to work on this bug too, and this bug is mostly
for tracking purposes.

Closing as WONTFIX as RHEL3 series will only be taking critical fixes.
