Comment 23 for bug 1428121

This is not a deadlock, just a lockdep warning that is unrelated to audio (i.e. a separate bug). If you want, I will blacklist the iwldvm module so that you don't see this.

As for my earlier comment about general IRQ problems - I stand corrected. This IS RF interference. In pulseaudio -vvv log, I see front headphone jack status changes that correspond in time to the glitches. However, this computer's case does not have frnt panel audio jacks, so I left the motherboard pins that should lead to the front panel audio unconnected to anything. And the keyboard becomes non-lagged if I shift it a bit on my table. Also, the Dell monitor sometimes shows some spurious light near its sensor "buttons". So, I now believe all of this strange activity is actually unrelated to the HDMI bug.
