Even I argued quite different in the old thread, I must recommend to stay away from T-series. We have an open prio1 SR (started 12-May-2010 !) - Solaris and Oracle development is involved, but still no resolution. (Communication is complex in such an issue, but I'd say, they still does not know what's going wrong) if someone wants to track it check for Bug:9714309. As it's still open I cannot tell the root cause or fix, but it's something about authentication in cssd - I could reproduce it with CRS stack or 'single node' (just ASM and RDBMS). everything in 11.1.0.7 - latest PSUs.
