Summary: Docking problems with Sony Vaio VGN SZ483N laptop Product: ACPI Version: 2.5 KernelVersion: 2.6.25-rc8 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Config-Hotplug AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] Latest working kernel version: None Earliest failing kernel version: 2.6.25-rc8 Distribution: Ubuntu Hardy Heron (8.04) Beta. Also fails with vanilla kernel Hardware Environment: Sony Vaio VGN SZ483N laptop + the corresponding docking station Software Environment: N/A Problem Description: I compiled the kernel from git following instructions from here: https://wiki.ubuntu.com/KernelTeam/GitKernelBuild Scenario 1: I boot the machine outside the dock. If I now dock it the ethernet adapter on the docking station is not recognized. Scenario 2: I boot the machine on the dock. The ethernet adapter on the docking station is recognized. If I now undock after pressing the undock button and redock again the ethernet adapter is not recognized. Scenario 3: I boot the machine on the dock. The ethernet adapter on the docking station is recognized. If I now undock without pressing the undock button then the machine hangs and requires a hard reset. Scenario 4: I boot the machine outside the dock and suspend it. If I now place it on the dock and resume then the ethernet adapter on the dock is recognized. Steps to reproduce: As above Docking and undocking works flawlessly under Windows Vista. The same buggy behavior is observed under Freebsd (see http://lists.freebsd.org/pipermail/freebsd-acpi/2008-March/004693.html). On the freebsd-mobile mailing list it was suggested that the \_SB.DOCK._STA method always seems to return zero (i.e. dock status method indicates that the system is undocked all the time) (see http://lists.freebsd.org/pipermail/freebsd-acpi/2008-March/004699.html). The attached script dock.sh scans the pci bus and powers them on. This seems to restore network connectivity after a redock but the in use LED on the dock does not light up. Furthermore /sys/devices/platform/dock.0/docked still contains a 0. Some discussion about the script can be found at http://ubuntuforums.org/showthread.php?t=666757 Please let me know if you need any further information. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
