Searching the Internet, many other laptops are affected (IBM and Dell). It seems to be a generic Linux kernel problem -- I could not see undock work on a number of distributions (Ubuntu, Fedora, Debian) that use a kernel above 2.6.23. I have first seen this in Fedora 9 and did not use Fedora 9 because of that. Fedora 7 (2.6.23.17-88.fc7 kernel works without a glitch). I have written a script that I hooked to udev and it is run on dock/undock events. The script (attached) disables/enables CDROM/DVD and enables/disables CRT. I want to stress that 2.6.23.17-88.fc7 works fine in all situations and combinations with respect to power on state (it does not matter if laptop is docked or undocked when I power it up), hotswap dock/undock, and hibernation (that is I can hibernate undocked and power on docked and it still gets dock event). I have been using it for half a year without a single glitch, regularly (each day) docking/undocking and hibernating multiple times. I have tried fedora 10 recently. What happens if that I press the undock button, in default kernel configuration, the laptop locks up immediately. If I specify the immediate_undock=N parameter to the docking driver, the undock event is handled, and the script that disables DVD/CRT works properly as before. However, most of the times when I dock, the dock event is not generated. Even when the dock event is generated, the USB ports on the docking station (keyboard and mice) are not reconnected (CDROM/DVD and CRT though work, thanks to the docking script). When undocking with immediate_undock=N, the flashing green led never stops to blink (even if my undock script has finished running). With 2.6.23.17-88.fc7, the led has stopped to blink shortly after pressing the undock button. I have also tried writing to /sys/devices/platform/dock.0/undock file from the undock script before exiting. This, however, seems to generate undock event in a loop and the script is called again and again.

Optionally, I also wanted to test the new kernel (better wireless, wireless leds, etc.) So, I selectively upgraded the pieces (to Fedora 10 versions) to try just the new kernel and X * pciaccess, drm, mesa, Xorg and drivers * mkinitrd, initscripts, upstart, udev, hal, util-linux-ng SysVinit-tools alsa mdadm * some other minot dependencies This has allowed me to stay with Fedora 7 while testing Fedora 10 kernel and X. While this is not a complete Fedora 10 system, I do not think it matters, judging from the Internet posts. Again, everything works fine with Fedora 10 components and Fedora 7 kernel.

This will generate a new undock event, and the next invocation of undocking script must take care not to do anything except returning 0 status. Failure to write to to /sys/devices/platform/dock.0/undock file will not complete undock properly and following dockings will result in not- operational HW as was previously described. On the other hand, failure to take care not to execute the undocking script on the following undocking events will result in a stuck system -- undock script will run again and again. I wonder why this undocking behavior/requirement is not documented. I also wonder what happened with Linux undock/hotplug after kernel 2.6.23 that immediate undocking has stopped working with IBM/Lenovo thinkpads? On my Thinkpad X61, ata_generic and pata_acpi drivers are used (not ahci) because the way the BIOS is configured. Maybe the changes are due to SATA hotplug and AHCI driver would work? I will continue testing. It is still a regression bug, since machine locks up and it used not to. Attached new dock/undock script makes dock/undock work again. It checks whether immediate_undock=N is set and uses lock files with time stamp to decide whether it is a first run or second "spurious" run. Tested with kernel 2.6.27.12-170.2.5.fc10.i686. Attached is also rc.local script that sets immediate_undock=N parameter depending on the kernel version.

I have set the BIOS to ahci mode. This caused the kernel to choose a built-in ahci driver instead. With AHCI driver, both immediate_undock=Y and immediate_undock=N work. So, the regression is probably due to "hotplug ACPI" sata thing. If ata_piix driver is used, we get a crash with immediate_undock=Y, which is a default.

Suspend locks machine after resume and hibernate locks machine while doing the hibrentate. This happens unless a scsi host rescan is performed before hibernation on the host to which CDROM was connected before undocking. This happens both for immediate undocking (when kernel detaches cdrom before udev is called) and for non-immediate undocking, when the acpi callback powers off cdrom and detaches it (and ultrabay if necesssary) in a proper way. Hibernation and suspend used to work without a hitch after undock at least with 2.6.23.17-88.fc7 kernel, so it is a regression. Attached are updated scripts that solve the hibernate and suspend problems after undock. rc.local -- we save what the CDROM host is if we boot docked. kernel version and use of ahci driver set either immediate or non-immediate undocking. dock/undock handler -- we support both immediate and non-immediate undocking. For non-immediate undocking, we try to power off the device and we detach it. We also try to save the CDROM scsi host before undock and after dock. suspend/hibernate/resume acpi handler (new): a sample script to suspend/hibernate/resume -- rescans the scsi host of CDROM device before suspend/hibernate.

It has the same problems. It seems the problem is not in the undock code but in the (s)ata hotplug layer. We have two problems here: * immediate undock locks up machine if ata_piix is used (bios is in non-ahci mode) * removal of device with echo 1 > /sys/class/scsi_device/${DEV}/device/delete followed by physical device removal will cause hibernate to lock if scsi host was not rescanned after physical device removal While ata_piix may be fixed by latest updates to work with immediate undocking, I believe the second problem is not related to docking. The fact that it happens with both drivers (ahci and ata_piix) and with both immediate undocking (when kernel removes the device and callbacks do not even see it) and with non-immediate undocking (when callbacks have a chance to power off the device and remove it) and the fact that hibernate locks up in "core" code (as far as I can see) indicate a generic problem with sata subsystem. It seems that something causes suspend handlers to lock up after device was removed and scsi host was not rescanned. I do believe it stopped working after hotplug sata support. It is probably easy to fix, too. If you think I am wrong, and there is a specific 2.6.29 kernel that fixes it, I am willing to try it. I have tried multiple times koji updates in the past looking for a solution, so it should not be a problem.
