And the annoying thing is...

<3> [383.431019] vcs0: heartbeat pulse did not flush idle tasks
<3> [383.431123] *ERROR* pulse active pulse_active+0x0/0x10
[i915]:pulse_retire+0x0/0x10 [i915]
<3> [383.431128] *ERROR* pulse  count: 0
<3> [383.431132] *ERROR* pulse  preallocated barriers? no

it is nothing more than bad timing; a missing CPU barrier. But where? I'm
running out of places to put them!
