X crashes on switching to console - intel_bufmgr_fake.c:1302: intel_bufmgr_fake_evict_all: Assertion failed

[Jeff Chua]

Swtiching to console resulted in X crashing. Same problem with trying
to suspend to ram.

X: intel_bufmgr_fake.c:1302: intel_bufmgr_fake_evict_all: Assertion
`((&bufmgr_fake->fenced)->next == (&bufmgr_fake->fenced))' failed.

Reverting back to older drm, mesa and intel_drv make the problem go
away. It seems the bufmgr_fake is causing this to fail,  but there're
too much depending on mesa, drm and intel_drv that I don't know how to
bisect it.

Thanks,
Jeff.
