Re: Nouveau not initializing correctly with stock kernel of NetBSD 10.0.0
The "core notifier timeout" and "base:-n timeout" messages happen all
the time on my system. The messages themselves seem to be detailed
internal messages and don't provide any link back to real-world, so
not very useful for debugging.
On my system at least the system is useable, modulo stalling at
unexpected times. See my PR kern/58053 for more details.
FWIW, my system behsves quite well when using firefox or xterms; it
fails misersably when I throw libreoffice and/or gnucash (both from
pkgsrc) into the mix.
You can most likely get a dumb framebuffer running if you disable
nouveau at boot. Just interrupt the countdown, excape to the boot
command prompt, and enter
userconf disable nouveau*
Then continue booting. You won't get any X accelleration... :-(
Good luck.

Hello All,
i am trying to get a framebuffer and possibly accelerated x11 on an
amd64 box using nouveau.
The GPUs i tried are an old PCIe 8400GS and a GTS250.
So far i had no success with a fresh install of NetBSD 10.0.0 and the
stock kernel, the monitor output freezes after this line, and never
comes back to life - i also cannot switch to other consoles or bring
up x11:

few timeouts:

My only succesfull option to get a working console output and to start
up x11 was to build a kernel without nouveau and only the generic
framebuffer. Of course then i don't have accelerated opengl in x11.
Can someone help or give some insights on what can i do to bring up
nouveau successfully?
Best regards,
Connor
