>Description:
Panic occurs during attachment of nouveau with GeForce GPU on amd64. As this occurs during install and boot the errors don't get captured in dmesg. I have typed in the message from Nouveau load. 

Suggest if there is way to capture the complete message. I can post dmesg of the pc running with nouveau disabled if that helps. Let me know

nouveau0: error: imem: unable to map PRAMIN BAR 2 : -35

Boot works with nouveau disabled in userconf. The driver used is genfb and I'm able to launch twm.

Also the same desktop works with nouveau driver in archlinux.


>How-To-Repeat:
Boot new image on GeForce GPU and post attachment of nouveau driver kernel panics.
