To undock, I press the button on the dock, the led blinks a couple times and turns green (also, dmesg tells me that all USB devices have been removed and they indeed stop functioning). Then I take the laptop out of the dock. Because the X61 lacks a CDROM drive, I bought a bay CDROM drive along with the UltraBase. But there is no CDROM inside it (so no mounted filesystems). I also have an USB keyboard and mouse plugged into the USB slots in the dock. So it seems the kernel *should* take care of those things without any userspace interaction. I just tested suspend/resume with the CDROM drive removed (an empty bay). Suspend/resume now works just fine, regardless how I dock/undock the laptop. Anyway, regarding the additional patches, which tree can I pull them from? (I'm eager to test them, I very much want my dock to work properly) thanks tom -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
