This is a new build -
NetBSD prv_netbsd 9.3_STABLE NetBSD 9.3_STABLE (GENERIC) #0: Thu Jun  8 11:18:12 UTC 2023 amd64

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

A similar ref. on an old ticket is here -

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.

Boot new image on GeForce GPU and post attachment of nouveau driver kernel panics.
