Having my own mixed results with rc4 as well. Similar... but different. More on that in a moment.
There are a number of kernel or driver related bugs with various freeze/hang symptoms (and likely various root causes). Since this bug has T400 in the name I'm removing my earlier duplicate flag. That way my fellow T400 owners have a simple place to track whether the issue we are all experiencing has truly been resolved or not. Given the number of hang/freeze related bugs I have looked at, I'd like to know if we are all experiencing the same symptoms. Also gives us a way to separate this issue from similar bugs with causes and fixes irrelevant here. With 2.3.38 - problem manifests intermittently. When it surfaces, every moment of fluid activity is followed by a moment frozen. Seems exacerbated by resuming from sleep or running from battery. Worst in the first 10 minutes after booting/resuming. Found a bug that causes the system to freeze every 30 seconds or so - symptoms here are distinctly different. With 2.6.39rc4 - So far, I have not experienced the same quick cycling freeze, but in the first few minutes after boot and resume the mouse and keyboard will stop taking input for longer periods, 10s of seconds to minutes at a time. However, only a handful of boots at this point. ** This bug is no longer a duplicate of bug 746084 [i945gm] Stuttering mouse with Natty Narwhal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/779753 Title: T400 laptop.
