\AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...
