[gouri <stephane.gourichon_lpad@xxxxxxx>]

Still happens on 3.5.0-41-generic.

I have recently observed a variant (and the symptoms are active now on the laptop I'm writing with).
When bug happens, plugging a device on one of the two USB3 ports powers the device but Linux does not detect anything (nothing in dmesg).
Plugging the same device on one of the two USB2 ports (which never suffered the problem) works normally as it always did.

Heres the output of lsusb when all 4 USB ports are free (nothing
plugged) :

Title:
  USB3 ports cause kernel crash and oops since 3.5.0-24-generic
  (3.5.0-23 ok), USB2 OK.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Summary: upgrading from 3.5.0-23 to 3.5.0-24 appears to reduce kernel
  stability suddenly from weeks/months to day or so.

  Context: Hardware Asus n55sf laptop. Plugging Galaxy Nexus phone via USB daily or so. Observed for months that sometimes USB breaks (e.g. optical mouse literally off, un/plug does nothing, reboot fixes), but no oops.
  Using suspend to ram regularly (~ daily). Typical uptime : weeks to 1-2 months.
  Using Ubuntu upgrades regularly.
  On 2013-02-01, upgraded to 3.5.0-23, no problem.
  On 2013-02-21, upgraded to 3.5.0-24.

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or
  System -> About Ubuntu

  12.10 AMD64

  2) The version of the package you are using, via 'apt-cache policy
  pkgname' or by checking in Software Center

  LC_ALL=C apt-cache policy linux-image

  linux-image:
    Installed: (none)
    Candidate: 3.5.0.25.31
    Version table:
       3.5.0.25.31 0
          500 http://fr.archive.ubuntu.com/ubuntu/ quantal-updates/main amd64 Packages
          500 http://security.ubuntu.com/ubuntu/ quantal-security/main amd64 Packages
       3.5.0.17.19 0
          500 http://fr.archive.ubuntu.com/ubuntu/ quantal/main amd64 Packages

  3) What you expected to happen

  No oops, no crash.

  4) What happened instead

  On 2013-02-22 (that is kernel update + 1 day), observed kernel panic: switch to text mode with panic report (but X mouse cursor still visible), led blinking. Text says : fatal exception interrupt.
  Action : taken photograph of screen (can join if useful), power cycle machine.

  On 2013-02-23 (that is kernel update + 2 days), observed kernel oops: switch to text mode with oops report, but X mouse cursor still visible and music still playing.
  Action : taken photograph on screen (can join if useful, but you have dmesg attached so probably not useful). Observed that vt-switching key combinations could restore display. Not rebooted system (using it to write this very report) but several features disabled (laptop-integrated card reader, USB mouse). Lsusb still reports in-laptop bluetooth device as present but bluetooth-sendto cannot detect Galaxy Nexus nearby when doing proper steps.

  Considered actions:
  * continue normal use to confirm / narrow oops circumstances
  * downgrade to 3.5.0-23 to confirm symptom disappear

  Thank you for your attention.
