Title:
  System hangs randomly in Karmic 32 bit

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I am using ASUS K40IN Notebook with Intel Core 2 Duo T6670 processor. This notebook is based on Nvidia MCP75 Chipset. 
  Ubuntu 9.10 32 bit with all updates as on Dec 18

  There was a kernel panic issue with Jaunty
  https://bugs.launchpad.net/fedora/+source/linux/+bug/440310 earlier.
  Mentioning here to help you guys to find any correlation.

  The system hangs at random intervals. While using Firefox or when left
  idle or when using gedit. The keyboard/mouse are not responsive and
  the display is also frozen. The only way to recover is to do a hard
  reset. Running Nvidia driver 190.53.

  In the syslog there is no log captured when the the system hanged. The
  system hanged at ~ 18:48. The complete log is attached.

  Dec 19 18:48:50 MyBook NetworkManager: <info>  (wlan0): supplicant connection state:  group handshake -> completed
  Dec 19 18:50:37 MyBook wpa_supplicant[1098]: CTRL-EVENT-SCAN-RESULTS

  Right now installed linux-backports-modules-karmic to verify if there
  is any issues with the ath9k drivers in ubuntu and the newer
  backported version resolves the issue.

  Do let me know if any futher information is required.
