I have successfully installed wheezy (debian-7.2.0-sparc-DVD-1.iso)
today to SF V215 hardware. Installation went clean. Upgraded to
unstable, now running 3.14-1-sparc64-smp . Meanwhile compiling 3.14.4
kernel sources as a test with gcc-4.9. Going to leave this machine
running, just to see how stable it will be.
