AT91 is looked after carefully, yes it is.

The thing is that CAP9 SoC (the defconfig that you are using)
has been obsoleted then removed for 3.4:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9918ceafd4a9e013572e03983f528017c29bb1cb

Defconfigs for AT91 may need some update though.
