Comment 14 for bug 585765

I believe I see both of these conditions on the Intel dual-core Atom N330 motherboard.

I have a monitor with both DVI and VGA inputs. The board in question uses the VGA input. Fairly frequently, when I switch from DVI use back to VGA use, the screensaver is active. But the system is frozen. Pressing the CAPS LOCK key does not light the caps-lock light on the keyboard. The mouse does not work. At first, I thought USB was dead, but I cannot ssh to the box and a ping after that results in the report the system id down. A front-panel reset is all that revives the system. This is not new with 10.04, but seems very frequent with 10.04 now.

A second observation of a different scenario is that at times I seem to be unable to use the keyboard, nor can I use the mouse "inside an application window", but I can use the mouse to launch new applications. If I select the System Monitor, for example, it will launch, but I cannot select a specific process. However, I beleive that when I used a right-click, things started working again (memory foggy - it was late).

Most, but not all, of my lockups involve Thunderbird email being active, but not all. I also had VirtualBox installed, until I read this thread moments ago. Also, on a probably-unrelated sidenote, I use a ReadyNAS NAS unit. At some point, once of my systems, possibly this one, started waking the ReadyNAS every few minutes. I don't know if the nfs driver is doing something strange on this host, but that was not the normal ReadyNAS behavior on a system that was sitting idle.
