The T5120/T5220 systems Sun recently announced are some of the first systems to come out of Sun using Fully Buffered DIMMs (FB-DIMMs). This new technology presented some new diagnosis challenges for us, but very recently, CR 6536482 – “diagnose FBR and FBU errors to branch” was putback into Solaris 10 (it’s been in OpenSolaris for a few weeks now). A patch will be coming soon, and while I don’t know the patch number, it’ll almost definitely be an update to 119578.
