Comment 105 for bug 185470

Ubuntu Intrepid 8.10
2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux

Intel 3945 (iwl3956) just stopped working. I had no problems with this driver since I've installed Intrepid Alpha and today when I was working CPU loadsuddenly become very high, my internet connection was lost and I cannot make it to work since then.

No upgrades were running. No system programs were running. No configuration files changed. Nothing. It simply stopped working.

Here is what I get in the logs:
