Since upgrading to jaunty 9.04 on a Lenovo X301 with Intel i915 graphics I am having kernel oops where the screen display, mouse pointer and keyboard lock-up. Everything else operates (that I can see via network interface), but no keyboard combinations cause any reaction. Below is the relevant /var/log/messages section. Is this related to this bug?
