I can confirm debug symbols is still in the kernel, but that is most
likely used for backtraces and debugging when a kernel panic happens.
This is instead of asking the user who had a kernel panic to rebuild
with debugging to debug it.

PREEMPTION as I understand it should have been removed from the kernel
config file.  It should have been removed from the GENERIC config file
after RELENG_8_0_RELEASE tag is made.  I don't know what your tag is
when you update.  Perhaps you're copying or using a config file from
the BETA or RC days?


I'll help until I can't help no more with your issue.
