** Description changed:

  Wireless with the BCM4312 adapter connects, runs several minutes, and
  disconnects unexpectedly with Ubuntu Jaunty (9.04) Alpha 4 on an HP 2133
  MiniNote laptop.  The same laptop runs wireless flawlessly under Ubuntu
  Intrepid (8.10). I only have wireless issues under Jaunty. Once it has
  disconnected, I'm unable to reestablish a connection w/o rebooting.
  
  Note that the laptop is configured to dual boot between Intrepid and
  Jaunty so its easy to run A/B experiments between the two releases.
  
  All this takes to reproduce is to boot Jaunty with the B43 driver, bring
  up wireless, and then wait 5 or 10 minutes. I've hit this at home, with
  WEP encryption, and at work on an open guest network so its not the AP.
  The wireless works fine for several minutes, disconnects, and then won't
  reconnect
  
  I'm running the latest Jaunty (Xubuntu) packages as of this morning
  (2/20/09) and the problem still occurs. I don't know if this is a
  network-manager issue or a driver problem. Here are some chunks of data
  to start the triage

  Feb 17 08:23:09 Polaris kernel: [ 2519.508117] b43-phy0 ERROR: You must go to http://linuxwireless.org/en/users/Drivers/b43#devicefirmware and download the latest firmware (version 4).
  
  I considered loading a different version of the B43 firmware as
  suggested but the firmware stored under /lib/firmware/b43 is identical
  between Ubuntu Intrepid and Jaunty. (I binary compared all the files and
  verified each uses the same firmware version (broadcom-
  wl-4.150.10.5.tar.bz2). The install_bcm43xx_firmware.sh scripts in
  Intrepid and Jaunty are also identical.
  
  So, I don't think this is a firmware issue despite the fact the driver
  wants new firmware. This firmware is fine in Intrepid. I think something
  else in the b43, wl, or ssb driver has regressed. Or, perhaps there's
  been a regression in network-manager.
  
  
  I'm happy to help any way necessary to find this bug.
