Comment 3 for bug 128617

Today my keyboard and mouse completely froze again. The Cursor on screen was still blinking. But I couldn't do anything other than turn the power of.

This is the error message from /var/log/messages
Sep 13 08:52:53 samson kernel: [ 6208.228000] ACPI Exception (evregion-0424): AE_TIME, Returned by Handler for [EmbeddedControl] [20060707]

I don't know if this is realted to Bug #65999 ... there is a similar ACPI Error. But I run KDE and not Gnome, so the Gnome-Power-Manager should not be the culprit. In addition my battery was removed and is still lying in the closet and correctly detected as "not present".

This happens all of a sudden without noticeable warning. I have the feeling, it is somehow triggered by my touchpad, well on the other hand, I always detect the error, when I want to use the mouse. I never had the keyboard stop first. If I don't restart immediately, the four lines above are repeated every 30 seconds until I power down. In the last seven days this happend 3 times.

Anyone reading this? Any ideas?

BTW: A new kernel-update
