Subject: 2.6.32: Attempted to kill the idle task?

Hi,

we have a Debian/lenny system (Dell R410) with its "latest"
2.6.32+27~bpo50+1 installed. From time to time the system tends to oops.
Can someone have a quick look at the following, if this makes sense at
all? I suspect the "real" oops message has scrolled away, but this is
all we got so far:
