Hot Swap support problems
 
Hi all
I have a problem writing a hotswap cPCI driver .
It works fine on a PCI card and if i plug the card before booting.
But if i unplug it and plug after booting i can't see correctly the card even with lspci:
I don see it at all if i plug it after booting and i see a device with vendor and dev ID FFFF if i unplug the device after boot.
the output of lspci -vv is below
my dev is 04:0a.0 and it sit on 03:04.0 PCI bridge
