[gentoo-user] firewall -> kernel hardlock error

[gentoo-user] firewall -> kernel hardlock error

[Corbin Bird]

Getting an error with kernel 4.1.28 ( USE="experimental symlink" )
The firewall ( 2 different packages tried ) locks up the machine during 
boot.

The old kernel ( 4.1.27 ) worked with no errors.
I copied the /usr/src/linux/.config file over from kernel 4.1.27.
Used "make menuconfig" to check if changes were needed.
Recompiled 3 different times, minor changes, same result.

reinstalled iptables, nftables, and ran "perl-cleaner reallyall".

Always locks up after rules compiled / starting to initialize iptables.

The firewalls tried :
arno-iptables-firewall, shorewall

Part of the kernel 4.1.28 change-log :

I suspect this may have something to do with it.

Is anyone else seeing / experiencing this problem?

Try 'make oldconfig' instead.
