Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Philips i386 PC with rt2x00 pci is suffering loss of WiFi connectivity
  after installing 15.04 Beta.

  The system did work correctly with older Ubuntu versions (like 12.04)
  and had this problem show up after upgrading to Trusty (as I already
  reported in bug #1318837). Using Trusty the problem went away when
  switching from the stock 3.13.0-XX-generic kernel to builds of newer
  kernels (like 3.14.1-031401).

  Now the same problem shows up again after installing Vivid Beta. It seems to be the same problem reported for other Ubuntu releases (see bugs #1318837 and #1383555) and also the same problem of this upstream kernel bug:
      https://bugzilla.kernel.org/show_bug.cgi?id=61621

  Someone on kernel's bug mentions turning off MSI interrupts and I can confirm it did change the situation:
  - normally the system looses WiFi connectivity mere seconds after boot (eg. can't ping anything after boot)
  - if I boot with "pci=nomsi" the system will remain connected to the WiFi for a much longer period (eg. I am able to apt-get install something after boot)
