[Toyota4Runner <1176577@xxxxxxxxxxxxxxxxxx>]

Just upgraded 3 machines to 64bit 13.10 and am still being flooded with
the message when I do a dmesg.  The only way I can stop it is by
blacklisting mei and mei_me, as within minutes dmesg is full of the
reset messages and doesn't contain any useful info any longer.

Title:
  mei unexpected reset in kernel 3.8

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” package in Arch Linux:
  New
Status in “linux” package in Fedora:
  Unknown

Bug description:
  Right after upgrading kernel from 3.5 to 3.8 (Ubuntu 13.04), the
  syslog got flooded by a large number of such messages:

  (cut)
  May  5 15:33:15 compaq-aldo kernel: [  205.064042] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
  May  5 15:33:21 compaq-aldo kernel: [  211.076029] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
  May  5 15:33:27 compaq-aldo kernel: [  217.088035] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
  May  5 15:33:33 compaq-aldo kernel: [  223.100039] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
  May  5 15:33:39 compaq-aldo kernel: [  229.112045] mei 0000:00:03.0: unexpected reset: dev_state = RESETING
  (cut)

  This was associated by non reliable ethernet functionality, i.e.
  transfer of large files from my Ubuntu box to a local NAS connected
  via ethernet got hanging with no other apparent errors or diagnostics:
  nautilus copy just stopped transferring data, leaving the copy window
  there with the progress bar stopped.

  I tried to reboot, but this behaviour is perfectly reproducible.

  This is one of the first syslog lines got from that kernel:

  May  5 15:30:15 compaq-aldo kernel: [    0.000000] Linux version
  3.8.0-19-generic (buildd@roseapple) (gcc version 4.7.3 (Ubuntu/Linaro
  4.7.3-1ubuntu1) ) #30-Ubuntu SMP Wed May 1 16:36:13 UTC 2013 (Ubuntu
  3.8.0-19.30-generic 3.8.8)

  I attach the whole syslog from boot of that kernel.

  On the same box, launching a previsous kernel (3.5) works flawlessly.
  For the time being, I removed 3.8 kernel from my box, now running 3.5.

  Kind regards
  Aldo
