>Description:
Page fault in ffs_getextattr (generic_bcopy). After that the following 
had been written to the console.

>How-To-Repeat:
 	Access to acl info on a file from samba after heavy io ( in less than 
	a day) on this system. The same kind of disk corruption might appear 
	under other circumstances.
>Fix:
	temporary solution disable acl
