Rebuilding ipw3945 and tp_smapi, the two modules, as usual after building new kernel(2.6.23), but it failed during compilation with sandbox error. ipw3945 and tp_smapi can emerge under kernel of 2.6.22-gentoo. This bug resembles the bug 195581. I am told that maybe I would emerge the both modules successfully with FEATURES="-sandbox", however, this is not a good solution.
