I have been running Suse for a couple of years on a particular machine. After the last upgrade everything stopped working. Opensuse 10.2 does not recognise any PCI device. lspci gives me no output at all.

I found a difference in the dmesg output between a working version (10.0) and the non-working version (10.2)

In 10.0 I have a message "Allocating PCI resources starting at 20000000" In 10.2 this becomes "Allocating PCI resources starting at 30000000"

I do not know what this actually means, but maybe it is the cause of the problem.

Does anyone know what this means or have a suggestion how I should proceed ?

Any input is highly appreciated.

Does OpenSuse include the hwinfo utility? It was included in earlier (8.x and 9.x versions) of SuSE. If you have it, try '/usr/sbin/hwinfo --pci'. It should list components of the PCI system, including driver info. Pay attention to the Driver Status line. It should tell you if the required driver(s) is/are active.

OpenSuse does include the hwinfo utility. I like the --pci option you pointed out. In version 10.0 it gives me a nice list of all the devices and their driver status.

However in version 10.2 it gives no output at all when used with the --pci option.

Strange, I expected that it would produce something. When I use lspci -H1 it gives me a nice list of all the devices, however lspci -n produces no output.

After extensive googling I found out that the -H1 options just probes for hardware and lists everything it finds. The fact that -n produces nothing seems to indicate that the kernel does not find the hardware. So I think the problem is in the kernel.

Any ideas ?
