Hi Chatty

If I have to be honest I'm surprised it works at all (considering the issues nvidia had with those cards)

* Can you please confirm if the blob (proprietary driver) works fine with your card

After a quick look I've noticed that

* Nouveau is using the vbios fetched from the PCIROM
* The vbios does not appear to be correct

As a workaround can you try appending the following to your kernel command line

nouveau.vbios="pramin"


It will tell nouveau to use the PRAMIN vbios, thus possibly resolving some of your problems

Note - I seriously believe that there is a hardware problem with your card considering the hardware issues that have been noticed (and confirmed in the linked
document)
