Bug Description
Just bought the Sony docking station for the Vaio VGN-SZ3XWP . The docking station contains a PCI-Express Yukon (using sky2 module) Gigabit Ethernet Card additional to the onboard Yukon Ethernet card and Wifi. When cold docking the card is detected fine and reverts back to normal when cold undocked. However when hotdocking the PCI card isn't detected.
Have tried to hack around the problem with the following method;
0) Start laptop undocked. Dock. lspci is missing dock network card, however scanpci finds it. Simple reloading the sky2 module doesn't detect card (as I assume its looking at the same thing as lspci)
1) load fakephp kernel module.
2) "echo 1 -n > /sys/bus/
3) lspci now displays docking station network card
4) sky2 module refuses to enable the PCI card complaining that;
PCI not enabled due to 0 resources collisions.
I figure this is probably due IRQ conflict, and /proc/pci reports that the docking station network card is on IRQ 0... which would obviously kick up a stink
5) I hit a proverbial brick wall at this point, as I cant seem to work out a way to change the IRQ for the card, except for hacking the driver, which I dont really feel qualified to do.
Hot undocking can result in a kernel panic if failing to rmmod sky2 first, but after undocking then redocking the dock network card fails to be detected (see above)
