Hi Greg, Thanks for the warning :) Yes, we are using "old" 2.4 kernels for our developments and didn't migrate to the newest kernels yet. We are developing complicated medical machines with proprietary hardware. For our purpose pci_find_device() is ABSOLUTELY legitimate as probably for many "old timer" kernel module developers :). Anyway, thanks for the advise I'm looking forward to learn new kernels.

Ick, NO!!!! Do not use pci_find_dev() to get your pci device you want to bind to. Use pci_register_driver() and friends instead to register a pci driver with the pci core. That way your driver will work properly with hotplug systems, and with the 2.6 kernel. Please read the pci.txt file in the Documentation directory for more information, and move your drivers into this century... Oh, and pci_find_dev() will be going away soon, you have been warned. greg k-h -- Kernelnewbies: Help each other learn about the Linux kernel.
