Description of problem: I'm running always into the following problem using Red Hat Enterprise Linux 3 Update 3 at a Itanium 2 (IA64) machine, to be exact it's a HP Integrity rx 7620 server: --- snipp --- [root@rhel3 root]# lspci pcilib: Cannot open /proc/bus/pci/70/1d.0 lspci: Unable to read 64 bytes of configuration space. [root@rhel3 root]# --- snapp --- Other information about the system which are maybe usefull: --- snipp --- [root@rhel3 root]# ls -la /proc/bus/pci/70/* -rw-r--r-- 1 root root 256 Oct 19 07:44 /proc/bus/pci/70/01.0 [root@rhel3 root]# [root@rhel3 root]# rpm -q hwdata pciutils kernel --qf '%{name}-%{version}-%{release}.%{arch}\n' hwdata-0.101.12-1.noarch pciutils-2.1.10-7.ia64 kernel-2.4.21-20.EL.ia64 [root@rhel3 root]# --- snapp --- Version-Release number of selected component (if applicable): pciutils-2.1.10-7 How reproducible: Everytime, see below. Steps to Reproduce: 1. lspci or: 2. lspci -vvv and: 3. Get the error. Actual results: No really usable lspci output. Expected results: Usable lspci output as normally given.
Created attachment 105424 [details] strace of lspci
Created attachment 105425 [details] 'cat /proc/bus/pci/devices' output
Kernel appears to have an inconsistent view of the pci space.
Oh btw, we also have the same problem at a HP-Superdome Itanium 2 (IA64)...and this is very annoying.
Ping?
sorry, haven't had a chance to look at this...do you know if this was working on Update 2?
