dmesg without nouveau.noaccel=1
Happened to get 2 FX4500's for my PowerMac G5 11,2, but it didn't seem willing
to cooperate.
Without nouveau.noaccel=1 in the kernel parameter, the system starts fine, but
X would only work with fbdev driver - as GPU locks up at early stages of
startup (dmesg attached above).
With nouveau.noaccel=1 in the kernel parameter, system starts fine without the
lock up message, but X will **still** only work with fbdev - using nouveau with
result in a looped output of the following message:
"nouveau 0000:0a:00.0: DRM: 0x13DC: Parsing digital output script table"
And the system is inaccessible, this also appears to hang any `systemctl stop
lightdm` operation and even the `reboot` command itself.
---------------------------
Xorg-Server version: 1.18.4
Kernel version: 4.8.6
xf86-video-nouveau version: 1.0.12
---------------------------
I would happily donate one of my FX4500's to one who's willing to investigate
this issue.</pre>
