Re: Nouveau not initializing correctly with stock kernel of NetBSD 10.0.0

Hello Paul,

thank you for your insights.

On my box after the console has freezed, there is no way to continue
or load up x11 as it does for you - but unusable as you report.
I can then only ssh into the box to shut it down again.

So it seems nouveau is in a non-working state on netbsd 10.0?
Was it working in the past and in what release?

Best regards,
Connor
