Hi folks,
I've notice that on x86_64, the way in which we walk the stack has
changed and this breaks backtrace() on mainline kernels. There are a
couple of dependencies that make coping the kernel's show_trace()
function not very straight forward. My hack seems to partially work but
also crashes the system from time to time. Has anyone experience this
or have a fix available that would work with 2.6.16 kernels?
Thanks
