Looking back at your original post ... maybe you should try a non-Gentoo
kernel. Gentoo doesn't have the greatest reputation for stability, and
on a non-mainstream architecture like sparc64 it'd likely be even buggier
than its usual reputation. The symptoms you cite are consistent with a
disk operation getting stuck in the kernel, and a system that locks up
to the point of requiring a hard reset sounds even more like a kernel
problem.
