In general, 39-rc2 seems pretty flaky, but on this boot, this is the first kernel splat. I had reloaded our user-space network-config DB, which would have deleted and created some VETH and MAC-VLAN interfaces, and a bunch of protocol sockets, virtual-routers (xorp with unique routing tables) etc. BUG: unable to handle kernel paging request at 50435453 IP: [] __kmalloc_track_caller+0xd8/0x117 *pde = 00000000 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1f.2/host0/target0:0:1/0:0:1:0/block/sda/sda1/stat Modules linked in: xt_CT iptable_raw xt_DSCP xt_dscp xt_string xt_owner xt_NFQUEUE xt_multiport xt_mark xt_iprange xt_hashlimit xt_connmark xt_addrty] Pid: 12747, comm: xorp_rtrmgr Not tainted 2.6.39-rc2-wl+ #56 To Be Filled By O.E.M.
