Please also see Bug #616947 I have a very similar problem as described in in this report as well as in Bug #616947 which may be both related to each other.
When systems freezes, caps lock panel flashes, which refers to a kernel panic. Screen gets blank and input of mouse and keyboard is not possible. The problem occured only recently and was reproduceable when under heavy network traffic. When using the network cable, everything works fine. I am using an IBM Thinpad T43 with an Atheros chipset. System is LTS 10.04 and updated. -- Madwifi (atheros) driver malfunction induces a system freeze https://bugs.launchpad.net/bugs/276445 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
