I'm not an expert, but I play one on the web. Here are
a couple ideas that may or may not resemble actual good ideas:
1. reduce the optimization from -O2 to -O1 when building the kernel
2. try gcc-3.3.1. Can't hurt, and who knows, maybe it'll help.
You can build it yourself fairly easily; see http://kegel.com/crosstool
