I've had 3 oopses in the last week that I've been playing with selinux.
ksymoops decoded results are attached. The first occurred when I was
trying to reload the policy:

Nov 21 19:33:24 bench3 kernel: ss:  loading policy configuration from /ss_policy
Nov 21 19:33:24 bench3 kernel: security:  4 users, 5 roles, 349 types
Nov 21 19:33:24 bench3 kernel: security:  29 classes, 60594 rules
Nov 21 19:33:24 bench3 kernel: Unable to handle kernel paging request at virtual address 465ec21c

The system was still useable but attempts to reload the policy were
hanging so I rebooted.

The other two happened when nobody was doing anything with the system
except cron running the normal stuff.

Nov 22 14:40:00 tracy kernel: task_precondition:  assigning context system_u:system_r:crond_t to pid 1620 exe=/usr/sbin/crond
Nov 22 14:40:00 tracy kernel: Unable to handle kernel paging request at virtual address 00732528

Nov 22 14:41:00 tracy kernel:  <1>Unable to handle kernel paging request at virtual address a8d4b5ec                                                             

After this the system was hung solid, no ping or anything.
