Hi,

I after running it during the weekend on my laptop I got several oopses. 
I already applied this patch (from Andrew Morton) to make powermanagement 
(acpi or apm) working at all:

--- 25/fs/binfmt_misc.c~bm_register_write-locking-fix        2003-10-25

1.) This happens from time to time, maybe triggered by acpid?
