IMHO, problem is in a *drm_irq.c*:
[...]
static void drm_update_vblank_count(struct drm_device *dev, int crtc)
{
[...]
cur_vblank = dev->driver->get_vblank_counter(dev, crtc);
[...]
where it submits crtc==0 - index of first available pipe instead of
index of first active pipe. perhaps if enabled only one pipe it assume
that it has index 0 (FIX ME)
