This problem did occur in a release prior to vivid.

It's hard for me to report exactly when the problem started occurring,
because most of the time I use ethernet, and there seem to be some
wireless networks which are more likely to tickle the problem than
others.

Title:
  iwl3945 on X61T crashes with Error sending C_POWER_TBL: time out after
  500ms

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After using wireless for some period of time, it stops working. dmesg
  report is attached. Rebooting the machine makes the wireless driver
  work again (for a little bit anyway). I haven't checked if it's
  related to suspend/resume, but I use this a lot. I can try bisecting
  for a kernel which doesn't have this problem, although between when I
  started having problems, I upgraded to Vivid (which didn't fix the
  problem.)
