Chris,

I'm seeing similar oopses and WiFi problems with my ThinkPad W700. The
oopses seem benign, but the WiFi dropouts are very annoying. They seem
related to overall system "pauses" where everything stops until I click
or move the mouse, or generate some other interrupt. Everything was fine
with Fedora 10. These pausing and dropout problems made Fedora 11 almost
unusable. I'm installing F12-Alpha now hoping upstream patches to the
kernel have fixed things. There seems to be some improvement to the
WiFi, but the pauses are still there. Haven't seen a kernel oops yet.
