I got an acpi notify handler. The notify is triggered when I call WMBC().
In this notify handler, I must re-call WMBC (with some other arguments, it won't
notify again this time).

If I do that, I'll get:
[  176.920391] ACPI Error (dswload-0802): [_T_0] Namespace lookup
failure, AE_ALREADY_EXISTS
[  176.920416] ACPI Exception: AE_ALREADY_EXISTS, During name
lookup/catalog (20100428/psloop-231)
[  176.920439] ACPI Error (psparse-0537): Method parse/execution
failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS
[  176.920469] ACPI: Marking method WMBC as Serialized because of
AE_ALREADY_EXISTS error

Could you attach the acpidump output?

Here it is, and here is the patch I did (I used the workqueue solution
in this one):

http://git.iksaif.net/?p=acpi4asus.git;a=blobdiff;f=drivers/platform/x86/eeepc-wmi.c;h=725239860bad8d97dabf8b3db4086d6df4b7820b;hp=0d8217d1478028071859ba1a503ba226b3cb33a0;hb=1eac4d6a6fb632314a464e7d52e1dcb1e4780931;hpb=5c5d1a036bb7d38153c6d2102767ef51e5d94ce3

(check eeepc_rfkill_notify, it's triggered when the wlan rfkill is
blocked: WMBC is called to disable the wlan card, it send a
notification, the handler is called, the handler want to check the
wlan card status, it calls WMBC again).
Thanks;
