I would like to report a bug about the module acpiphp. I don't know if this is the right place, if it isn't please tell me where I should write and I will do it.
description: docking station hotplug working on 3.5.0 kernel but not in previous and next kernel releases hardware: sony vaio serie z SVZ1311C5E + Docking station VGP-PRZ20A distro: Ubuntu precise, kernels compiled from the source in kernel.org The problem is about connecting the docking station after the boot. with kernel 3.5.0: when I connect the docking station I can see the following log lines (dmesg): [ 2442.046921] acpiphp: Slot [1-1] registered [ 2442.046945] acpiphp: Slot [2] registered [ 2442.046968] acpiphp: Slot [3] registered [ 2442.047056] acpiphp: Slot [1-2] registered [ 2442.047066] acpiphp_glue: sibling found, but _SUN doesn't match! [ 2442.047169] acpiphp: Slot [1-3] registered [ 2442.047229] acpiphp: Slot [1-4] registered [ 2442.047300] acpiphp: Slot [1-5] registered after that all the devices are available in the system. I can use the external network, the bluray device, and the usb ports available in the docking station. if I unload the acpiphp module the hotplug doesn't work, meaning no log lines and devices not usable. with any other kernel (I tried also with 3.10rc5): when I connect the docking station I cannot see the log lines specified above, and the devices are not available. I tried with and without acpiphp loaded. I didn't tried with other 3.5 kernel versions. I tried with 3.7 and 3.8 and it is not working If I connect the docking station before the boot with a non 3.5.0 kernel and I unplug it I can continue to see the devices available but of course not working.
