B767 that lost primary instruments

[Capitano]

Could anybody clarify what happened to the ETOPS B767 (Martinair if I remember correctly) that went accross Atlantic a few years back, and had to land on Stby instruments in Goose Bay? I understand the A/C was then flown to Seattle for investigation as, obviously, it should have not lost the electrics resulting that only Stby systems were operational.

Is there any investigation report in the web that one could read?

Thanks to everyone contributing
