Behaviour still present on my SZ using 2.6.27-6-generic (has been dist- upgraded to 8.10 for testing).
Starting on dock gets dock GigE port. Pressing dock button the light on the dock goes out, and we get 'ACPI: \_SB_.DOCK - undocking' in kernel messages. No other message. Removing laptop hard locks. The only working solution for this is manual docking changes as follows: - apciphp must be loaded (is not by default) - Shut down the slot the extra gige nic lives in with `echo 0 > /sys/bus/pci/slots/4/power` (sky2 driver notes this and correctly handles the shutdown of just the extra NIC) - Force undock (turns off LED on dock) with `echo 1 > /sys/bus/platform/devices/dock.0/undock`. Stalls until lifted off dock. Redocking can be done by merely echoing 1 into slots/4/power (assuming apciphp is loaded), NIC will become available. /sys/devices/platform/dock.0/docked does not report correct dock status if you redock this way (always returns 0). It does report correct dock status if you power up on the dock (1), and issue the undock above (0). -- [Hardy] 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
