Please please try the following patch and see if it helps. and it would be great if you can attach the acpidump of your laptop.

This tries to avoid calls _STA, and still keep the device present check. http://bugzilla.kernel.org/show_bug.cgi?id=10431 Signed-off-by: Shaohua Li <shaohua.li@xxxxxxxxx> --- drivers/acpi/dock.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) Index: linux/drivers/acpi/dock.c =================================================================== --- linux.orig/drivers/acpi/dock.c 2008-08-27 14:38:44.000000000 +0800 +++ linux/drivers/acpi/dock.c 2008-08-28 09:33:02.000000000 +0800 @@ -604,14 +604,17 @@ static int handle_eject_request(struct d static void dock_notify(acpi_handle handle, u32 event, void *data) { struct dock_station *ds = data; + struct acpi_device *tmp; switch (event) { case ACPI_NOTIFY_BUS_CHECK: - if (!dock_in_progress(ds) && dock_present(ds)) { + if (!dock_in_progress(ds) && acpi_bus_get_device(ds->handle, + &tmp)) { begin_dock(ds); dock(ds); if (!dock_present(ds)) { printk(KERN_ERR PREFIX "Unable to dock!\n"); + complete_dock(ds); break; } atomic_notifier_call_chain(&dock_notifier_list, -- 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 -- 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
