[Bug 384167] [NEW] wl module causes hard lock

Public bug reported:

Binary package hint: bcmwl-kernel-source

Using the latest, as of now, version of dkms and bcmwl-kernel-source,
the wl module builds seemingly find. Doing a depmod -a and update-
initramfs cycle, the module loads on boot; the laptop (HP Mininote 2133)
WiFi light transitions to blue indicating that the driver loaded.

Upon kdm starting up, however, the entire system hard locks. The three finger salute does nothing, nor does <ALT-PRTSCR
N+(REISUB)>. The only way to recover is to force a power cycle.

Making things even more wierd, this is very repeatable; however, if one
keeps the cursor moving continuously using the integrated Synaptics
touchpad while kdm/X11 are loading, the system boots without locking.

In this latter case, the eth1 wireless interface shows in the logs, but
any attempt to interact with it, e.g. iwconfig, causes an immediate hard
lock.

This particular BCM4312 device worked well with ndiswrapper through
hardy and with the wl module in LRM in intrepid. It never worked with
the Jaunty kernels; which motivated my upgrade to karmic. Unfortunately,
it still does not work. Being a laptop, this is a serious regression.

Note that with the Jaunty and Karmic kernels, neither wl, nor
ndiswrapper, nor b43 work. With Intrepid and earlier, I used the VIA
modules for the Chrome9HC video. For the Jaunty and Karmic kernels, this
is not available from VIAarena, so I am using the openchrome module that
ships with Ubuntu.

Let me know how I can help as this is driving me (more) bonkers (than
normal :)).
