--- Comment #25 from Oleg Bulatov <oleg at bulatov.mobi> ---
Still present in 3.13.2-gentoo. I found that -EBUSY returns from
nv50_fbcon_imageblit.

Does it mean that the bug somewhere in nv50_grctx_generate? Just to be sure
that bug in this function, is it possible to replace it using data from
mmiotrace of nvidia driver? For me it is not obvious how to modificate
nv50_grctx_fill in that case, what nv50_grctx_init should write to *size and,
after all, may it help somehow?
