First I'm sending this to questions instead of stable because email to stable
doesn't seem to make it there...

This is just an FYI:

Accessing /dev/mem via a read operation (aka cat /dev/mem or dd if=/dev/mem)
hangs 4.5-stable. No panic ...

To be more precise what I typed was:

cat /dev/mem > /e/xxx
(in case it was the disk access is related to the hang).
