There's a known bug that will cause ipv6 interfaces configured via /etc/network/interfaces to fail to come up because IPv6 support is compiled in the kernel instead of as a module.

This is an issue on linodes since even on the Xen beta boxes, ipv6 support is compiled into the kernels.

In the meantime, this seems to override the errant behaviour:

edit /etc/modprobe.d/local (create it if it doesn't exist) and add the line:
Code: install ipv6    /bin/true
which basically tells modprobe to run /bin/true instaed of trying to actually load the module.
