That all cards do have different brands doesn't matter to the BIOS bug.
If there is a bug, which maybe is there since AMD delivered the structure for this Card and this BIOS, then it could be that this bug is related over more brands/various cards.
Maybe (I'm working at a electronic devices manufacturer) there is a SMD-Device with a failure.
That might explain (if so) why there are several cards all over the place, that seem to have this behaviour.
Maybe we will never find out (I do not hope that, but who knows?).
I'm searching.
The log is in progress, I'm waiting for the bug to occur.
The "fun" part (and the fact that for me it can't be the cards) is that even I did not activate gpu 0,2,3 in that session, if now I launch a new sgminer with them, they are only running at 2.0 (like after they get a drop), even if I did not use them previsously.
I have to do a coldreboot to recover my 0.2M on each 290, even on the one that did not be used previously.
That's why I was thinking that the problem is something triggered inside the program (or the os) and not inside the cards.
Here is the beginning and the end of the file. I killed the process juste after the drop. I activate only GPU1. Tell me if you want another part.
