    Built kernels on the server with native gcc 4.2.4 and 4.3.1 and repeated
    the build test. Both of them threw an Oops with traces like the ones
    we've seen before. Also, because now's about time to start shooting in
    the dark, I tried a cross-built kernel with CC_OPTIMIZE_FOR_SIZE
    disabled. That one Oopses too. Also I reseated the server's memory.

    Although I've been able to build kernels over NFS with 2.6.26 on the
    server, I've just realized I haven't tried to stress it much. I'll try
    a build loop when the server's running 2.6.26 this evening.
