[Bug 1247712] Re: Unable to install Broadcom STA wireless dirver on 3.8 / 3.11 kernel via jockey-gtk

  Thread Previous • Date Previous • • Thread Next 
** Description changed:

+ SRU request:
+ 
+ Please accept jockey_0.9.7-0ubuntu7.15 into precise-proposed.
+ 
+ [Impact]
+ 
+ Kernel versions higher than 3.8 fail to rebind the Broadcom device to
+ the driver thus compromising system stability. While rebinding is a nice
+ feature it can't come at the cost of system stability. For this reason
+ we'll disable this feature when dealing with Linux >= 3.8 and preserve
+ it in the other cases.
+ 
+ [Test Case]
+ 
+ Install and reboot into Linux 3.8 or higher (linux-lts-saucy or linux-
+ lts-trusty), then use Jockey to install the broadcom wireless driver.
+ Jockey will hang and the system will probably hang on shutdown.
+ 
+ [Regression Potential]
+ 
+ It should be minimal i.e. there won't be device rebinding on the livecd.
+ This, however, shouldn't be an issue since the open broadcom driver
+ should already work out of the box.
+ 
+ Furthermore the test suite now covers this test case.

  Affected chipsets:
  Broadcom 4365
  Broadcom 4313 [14e4:4727] (rev 01)
  Broadcom 43132
  
  The bcmwl (6.20.155.1+bdcom-0ubuntu0.0.2) cannot be installed on 12.04.4
  (3.11.0-15), 12.04.3 (3.8.0-29)
  
  Steps:
  1. Install Ubuntu 12.04.3 (or 12.04.4) + update
  2. Boot to desktop
  3. Install the Broadcom STA wireless driver via jockey-gtk
  
  Driver cannot be installed, jockey-gtk will stuck at "Downloading and installing driver"
  The last message from jockey.jog is:

Bug description:
  SRU request:

  Please accept jockey_0.9.7-0ubuntu7.15 into precise-proposed.

  [Impact]

  Kernel versions higher than 3.8 fail to rebind the Broadcom device to
  the driver thus compromising system stability. While rebinding is a
  nice feature it can't come at the cost of system stability. For this
  reason we'll disable this feature when dealing with Linux >= 3.8 and
  preserve it in the other cases.

  [Test Case]

  Install and reboot into Linux 3.8 or higher (linux-lts-saucy or linux-
  lts-trusty), then use Jockey to install the broadcom wireless driver.
  Jockey will hang and the system will probably hang on shutdown.

  [Regression Potential]

  It should be minimal i.e. there won't be device rebinding on the
  livecd. This, however, shouldn't be an issue since the open broadcom
  driver should already work out of the box.

  Furthermore the test suite now covers this test case.
