Not that I expect any details, but.... that sucked for ATI, because they had everything ready to go, and had *some* bug somewhere, that took them forever to find and correct.
Does anyone even have a guess? (AFAIR, they never said what it was)
If my memory serves me well, the bug was reported to be 3rd party libraries related to the (ringbus) memory controller which weren't properly fitting TSMC 90nm process, and had to be fixed.
