Hello Christopher

In principle I am of  course willing to do this test. But since this 
test will take quite some time I would first like to understand whether 
there is really a possibilitiy that the new kernel fixes this issue.

Facts:

  * Ralink RT 3290 works for me under .54, .55, and .56 (after having
    applied a workaround).
  * the RT module is compiled for every new kernel.
  * The kernels and the RT module are not incompatible as such
      o the issue was caused by changes in the kernel HEADER files
      o the "inline function" kmalloc_array in the kernel header file
        slab.h competes with an identical definition in the RT driver.
      o hence the re-compilation for new kernels fails (THIS IS A SIMPLE
        syntax error)
      o I described the details under
        https://answers.launchpad.net/ubuntu-certification/+question/238136

To fix this, several solution could be applied

 1. undo the change in the kernel header file slab.h -> I doubt that
    this has been done
 2. re-engineer the RT sources so that I can be successfully compiled ->
    since this an OEM module: I doubt that this has been done
 3. introduce "natural support" of the RALINK HW so that the OEM module
    is not needed anymore.

Has either of the three options above been implemented? Otherwise I 
doubt that testing the new kernel makes sense.

It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested.

Title:
  RT3290 12.04 new kernel

  - rebboot and WLAN function gone
  the last Kernel 3.2.0-54 was no problem with the Ralink Corp RT3290 Wireless 802.11 n 
  lspci still shows the chip
  iwconfig shows no wireless extentions 

  The Ralink is in many HP Notebooks like the HP 655
