I'm also seeing a kernel panic when trying to load a newer version of
the Broadcom driver on my HP dv8135nr system.

This driver (for the HP dv8135nr) works:

  Broadcom BCM43xx 802.11 Network Adapter Driver (4.40.19.0)
  ftp://ftp.hp.com/pub/softpaq/sp33001-33500/sp33008.exe

This driver (for the HP dv6110us) causes a kernel page fault with
non-sleepable locks held:

  Broadcom BCM43xx 802.11 Network Adapter Driver (4.100.15.5)
  ftp://ftp.hp.com/pub/softpaq/sp34001-34500/sp34152.exe

Note:  This driver has my adapter listed in the bcmwl5.inf file.
