It's very likely that most of the issues you've been seeing are due to the bugs in the exception reporting assembly code that Michael Karcher just fixed [1]. I'm currently preparing a test kernel which you can and should test. We need to verify the kernel on: - UltraSPARC I or II - UltraSPARC III - Niagara 1 (SPARC T1) - Niagara 4 (SPARC T4) > Having said all of that I wonder if anyone has run Linux on the more > recently built ORACLE S7-2 type servers?

Linux should run fine on the SPARC S7-2 at least inside an LDOM. For bare-metal, we might have to cherry-pick some patches from Oracle's UEK kernel.
