and there are a lot of kernel bugs in sparc64 port.

I have systems with wheezy where I saw some corrected ECC (console and logs).
But the main problem are the freezes - there is some discussion on
the sparc kernel over freezes under io load. So probably some of that
bugs are fixes in the 3.17 rc's > rc1 - will try when time permits.

Maybe, but I haven't see this kind of discussion for a long time. I cannot test 3.17-rc1 as sun4v support is broken (LSI SAS and cpu support).

And don't forget that some chipsets (psycho for example) are buggy. U80 triggers false ECC errors when system runs with 4 GB of RAM.
