7	After playing around with the acl rules, I isolated it down to the
8	domain line which seems to cause the problems.. take a default policy
9	line from the gradm2 tarball, add (probably with other users)
10
11	domain wargamers ul level0 level1 level2 level3 level4 level5 level6
12	level7 level8 level9 level10
13
14	then gradm -E -L /etc/grsec/blah, then gradm -D
15
16	The kernel should then panic as before (with edi == 0x6b6b6b6b)
17
18	Hope this helps,
