Public bug reported:

I have a laptop with WiFi card which uses bcmwl proprietary driver. When the 
driver is enabled I get large amount of xruns. 
This is message I get in jackd:
ERROR: JackAudioDriver::ProcessGraphAsyncMaster: Process error

This makes it unusable for any audio work with jack as the sound cracks.

When I disable wifi, xruns disappear. I checked /proc/interrupts - wlan0
and snd are on different interrupts.

Checked with both standard kernel and lowlatency kernel.

Using Ubuntu 15.04
