KEYDBG() macro executed only when net.key.debug is set to non-zero value. It
looks like your sysctl.conf didn't set it. Also, it looks impossible to get
page fault with fault address 0x28 in this line of code. I suspect, that you
have some sort of memory corruption. Not sure, is it hardware related or it is
overwritten by some code.
