<pre>I saw this on IRC:
10:59 #nouveau: < mupuf> ok
11:00 #nouveau: < blackiner> imirkin: i know you were messing around a bit on
nv4x video decoding stuff a bit back, did you have any patches that would have
affected a nv43 recently?
11:00 #nouveau: < blackiner> just tried out arch on my other machine, any vdpau
video seems to freeze the machine on it
11:01 #nouveau: < blackiner> but xv works fine
11:01 #nouveau: < imirkin> blackiner: there is no vdpau support for nv4x. there
is xvmc support however.
11:01 #nouveau: < imirkin> blackiner: i do think that some distros recently
started including libvdpau_nouveau.so though
11:01 #nouveau: < imirkin> which is probably why you've just started seeing
issues
11:01 #nouveau: < blackiner> yeah it seems to install all the vdpau stuff by
default
11:02 #nouveau: < imirkin> it's probably the case that vdpau is somehow broken
for nv4x
11:02 #nouveau: < imirkin> there's definitely no video decoding support in
there
11:02 #nouveau: < blackiner> I wonder if there is some init function somewhere
where it should just tell vdpau: No, not possible, please go away
11:02 #nouveau: < imirkin> but the presentation layer probably tries to do some
timing thing
11:02 #nouveau: < imirkin> and i've seen the timer stuff be broken on nv4x
11:02 #nouveau: < imirkin> well, i added that for nv3x
11:03 #nouveau: < imirkin> (well, i added a requirement for NPOT textures)
And I saw this in my dmesg with flash:

I think this issue crashed my machine as I was opening something in Youtube.
The relevant output was this:

feb 24 13:39:15 Charlie kernel: [sched_delayed] sched: RT throttling activated
