[Bug 1244085] Re: Bluetooth fails after suspend resume

  Thread Previous • Date Previous • • Thread Next 
Hi,

Unfortunately the problem persists on 3.12.0-031200rc6-generic too. I've
confirmed and updated the tags as requested.

Cheers

Kyle

** Tags added: kernel-bug-exists-upstream

** Description changed:

  Lenovo X200 will appear to suspend and resume correctly, but any attempt
  to use bluetooth will result in a kernel oops followed by a hard lockup
  a few minutes later. Below is some relevant output from /var/log/syslog
  and lsusb, and I believe the rest of my system information has been
  uploaded by ubuntu-bug.
  
  Regards
  
  Kyle

Title:
  Bluetooth fails after suspend resume

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Lenovo X200 will appear to suspend and resume correctly, but any
  attempt to use bluetooth will result in a kernel oops followed by a
  hard lockup a few minutes later. Below is some relevant output from
  /var/log/syslog and lsusb, and I believe the rest of my system
  information has been uploaded by ubuntu-bug.
