Hrm.... that is a separate bug that we should probably figure out.
Looks like some use-after-free when nouveau fails to come up (note the
poison 0x6b values in various registers). But the above patch will
hopefully prevent that situation.

Yes, that one prevents the "freq unknown" error!
It should probably be pushed to dave/linus for rc3.

With it applied nouveau loads successfully.

Yep, I enable SLUB poison on all my kernels with slub_debug=FZP

How much of the trace can be trusted as being real code and not some
remainder of non-overwritten data mis-parsed?

If it can be trusted, the point in nouveau_drm_probe() is within
alloc_apertures() which does not really make sense as efifb has already
been removed, thus we should see code happening after
remove_conflicting_framebuffers().

Probably SyS_finit_module() is the only relevant part of the stack-trace
and some module-assigned data has been double-freed/poisoned.

Thanks,
Bruno

OK, so it looks like here's what happens:

nouveau_drm_probe -> drm_get_pci_dev -> drm_dev_register->
nouveau_drm_load

The load fails. In its cleanup path, drm_dev_register cleans up
dev->primary/render/control and propagates the error. Reasonable
enough.

drm_get_pci_dev, in turn, calls drm_dev_free. The first thing that
does is... clean up dev->primary/render/control. So that's the most
likely source of the double-free.

I'm not sufficiently familiar with the drm internals to know which
function shouldn't be cleaning up what, but it definitely seems like a
problem. Dave, I leave this in your capable hands :)
