Second GPU won't work?

[alexdrans]

Hey guys, having a little issue, maybe someone knows what's wrong. I've been mining fine for the last couple of days under Windows using a single 5870. Today my second 5870 was delivered and I decided to use Ubuntu. I can get my first card running perfectly fine, but the second card either crashes my computer or runs at very low khash/s

I followed the Ubuntu 11.04 guide and I can get my first GPU to mine perfectly, but if I change the device to -d2 (from d1, I've confirmed that the second GPU is d2) it either doesn't display anything and the terminal crashes, or it'll display a 653khash/s or so.

Does anyone know what's wrong with this?

It seems that the card is actually broken
