The last patch is not a functional change, but a behavior change that
removes the L2FilterDiscards from being counted to match previous behavior.

Would you please do this:

script bt.txt kgdb /boot/kernel/kernel.symbols /var/crash/vmcore.0

Then, do 'bt', press enter until all display has finished, then exit
kgdb, and send me the result (bt.txt)?
