Can you do 'gdb kernel.debug' in your kernel build directory and then do 'l
*tcp_input+0x368' to determine which source line it is panic'ing at? This
might help us figure out what the unaligned access is so it can be fixed. If
you don't have a debug kernel, please build one and reproduce the panic to
get the updated 'tcp_input+0xblah' line and then do the gdb command with the
updated 'tcp_input+0xblah' bit. Thanks.
