Sorry I wrote _li_ and not _lis_ result is :
------------------------------------
...
exception+0x0/0x74
bad_page_fault+0x5c/0x60
handle_page_fault+0x7c/0x80
__wake_up_common+0x58/0xa4
... Oops kernel access bad area, sig 11

Hard reboot.

Result: the ibook wakes up, seems to be good.

Test 3 (two changes together): dont wakes up.

Please could confirm the _lis_ and not the _li_ at line 64?

Thanks.
