>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
