I poked around a bit and trapped the uevents generated when I dock or undock the machine (after manually loading acpiphp) using udevmonitor. I am attaching them.
As you can see when I undock the machine the ethernet card correctly generates an uevent but when I dock the machine back it is conspicuous by its absence. This might give a clue in further debugging the problem. I also checked the status of /sys/devices/platform/dock.0/docked and it contains the value 0 indicating that the kernel still thinks that the device is undocked. ** Attachment added: "dock.txt" http://launchpadlibrarian.net/12221679/dock.txt -- [gutsy] docking station hard freeze with vaio vgn sz483n https://bugs.launchpad.net/bugs/194617 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
