[Bug 1461738] Re: iwl3945 on X61T crashes with Error sending C_POWER_TBL: time out after 500ms

 

Edward Z. Yang, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/Kernel/MainlineBuilds ? It
will allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of
kernel-bug-exists-upstream.

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Thank you for your understanding.

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.)
