Bug#607879: System hangs up with mmap.c:873!
I can confirm this bug.
I created a Debian Live system based on Squeeze and on many machines the
system just hangs when shutting down.
My latest test was on a Dell Optiplex SX280. I will attach the entries in
kern.log and the output of lspci on this system.
