Bringing up an 801.2q interface via /etc/conf.d/net works fine, but attempting to stop the service appears to cause a kernel dealock that requires a hard reboot to recover from. The specific error is as follows: dylanv@dylan-1 lib $ sudo /etc/init.d/net.eth1 stop * Bringing eth1.4 down * Removing inet6 addresses * eth1.4 inet6 del fe80::211:43ff:fedd:90c/64...

This appears to be IPv6 related. Removing ipv6 from the kernel and adding -ipv6 to my USE flags and doing an emerge -uD --newuse world eliminated the problem.
