My debug shows something like this: * Is a control method * Method at AML address d08047a4 length 39D * Begin method parse Entry=3Dcff43904 obj=3Dcff4238c * State=3Dcff4ec00 * Completed one call to walk loop, AE_OK, state=3Dcff4ec00 * Parser exiting, status AE_OK * Begin method execution Entry=3Dcff43904 obj=3Dcff4238c * State=3Dcff4ec00 * Completed one call to walk loop, AE_CTRL_TRANSFER State=3Dcff4ec00 * Execute Method 00000000, current state cff4ec00 * State=3Dcff4e800 * Completed one call to walk loop, AE_OK, State=3Dcff4e800 * Parser exiting, status AE_OK * Starting nested execution, newstate=3Dcff4e800 * Completed one call to walk loop, AE_OK, state=3Dcff4e800 * Completed one call to walk loop, AE_OK, state=3Dcff4ec00 * Parser exiting, status AE_OK And keeps doing this every time GPE08 is enabled. Any ideas ? Right now I have disabled the GPE and can trigger an enable= =20 via /proc, so if you need more info, please tell me. The hex dump at 0xd08047a4 + 1 shows something like: 5c 2f 04 5f 53 42 5f 50 43 49 30 50 43 49 42 42 52 47 42 60 79 60 0a 18= =20 60 0c 0b b1 20 00 60 70 0a af 5c 2f 03 5f 53 42 5f 4d 45 4d 5f 49 45 44 49 53 4d 42 52 0b 00 ff 60 0a= =20 00 0a 00 0a b2 a2 4b 35 91 5c 2f 03 5f 53 42 5f 4d 45 4d 5f 47 50 35 30 91 =2E... And now a stupid question: on the second line I believe it reads as=20 "Root" "Multiname" "3 Segments", but it looks like it has 4=20 (_SB_.MEM_.IEDI.SMBR). Is this correct ? --=20 =C1lvaro Lopes=20 --------------------- A .sig is just a .sig
