On my Thinkpad (using thinkpad_acpi), ACPI stopped working after a while, and I manage to track it down to a kacpid crash:

This is zen-sources, but I also see the same problem with gentoo-sources and git-sources.
I am trying to figure out what triggers the crash. Is there a quick way to monitor dmesg put up a notification on the screen that kacpi crashed?
