Hi,
I am not sure if this mail list is the proper place to report this bug,
but it is happened on my cavium octeon platform.
While doing stress test (more than 1500 new connections per second) on a
ssl proxy program (etunnel, which is written by me), I always got the
following kernel complain after 1-2 hours:
Kernel bug detected[#1]:

Any help will be appreciated, Thanks very much.
