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

[Connor McLaughlan <cont6pro3%gmail.com@localhost>]

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
