My old machine started getting a bit flaky, so I have kicked it off my
desk, but still wanted to get some nouveau bugs fixed on it. (In fact
it's easier now that I can reboot it more easily.)
So I put a spare old hard drive on it and rebuilt it, but I'm having
a heck of a time getting it working. Whenever it tries to load the
nouveau module, it blows up.
What's funny is that it *used* to work, but I re-downloaded all
the sources and rebuilt, so something might have changed.
The current kernel is 3.2.0-rc2-00097-g75b64de3, built from commit
75b64de35b70358b789bb8c8a3ec35b67734b725
"drm/nouveau/hwsq: remove some magic, give proper opcode names"
I finally captured the kernel logs when loading the module, as follows:
