Stuart Bishop, just to clarify, is wifi power management on when this
happens?

If so, does turning it off via the following terminal command change anything:
iwconfig wlan0 power off

Title:
  HP Pavilion 13-b208tu w/ Broadcom BCM43142 Wifi unstable, panics

Status in bcmwl package in Ubuntu:
  Incomplete

Bug description:
  This new laptop's wireless connection (HP Pavilion 13-b208tu, Broadcom
  BCM43142) is disconnecting every few minutes after coming up from a
  restart or shutdown. This corresponds to panics and tracebacks in the
  kernel log.

  The laptop was freshly installed with Ubuntu 14.10 (Utopic), and
  disconnections were seen. I then upgraded it to Ubuntu 15.04 (Vivid
  developement release), and am still experiencing the problem. The
  Broadcom proprietary driver is being used, and seems to be the only
  one available for this device.
