Test system.
kernel is 2.6.0-test1-bk (Fri, July 25), talking to a 2.4.21 kernel
with IPSec backport. IPSec is tunnel mode, ESP and AH with AES and MD5
for phase 1 and phase 2. PFS is off. default lifetimes. no modules
loaded on 2.6 kernel.
Linux 2.6 was running netserver as part of netperf testing. While IPSec
traffic was running, I issued a reboot on linux 2.6 box. That caused
the OOPS.
Also, /usr/src/linux is a symbolic link to the linux-2.5 bk tree, so
the ksymoops is working on the correct files.
