I use the pro-audio overlay only for some apps, then I inactivate it in the make.conf file and I use the package.provided file for these softs not to be seen when upgrading normally the rest of the softs. I use the stable branch of gentoo and ~x86 in the package.keywords file, and I avoid as much as I can using cvs versions. Also, I haven't had any problem of stability, especially with Zyn. For the kernel, I use a vanilla one, from kernel.org, that I patch myself (Ingo Molnar's patch, and only this one). IMHO, the problems you encounter seems to have nothing to do with the Tyan motherboard... Cheers, Y.
