This bug is a kernel bug rather than an mdadm bug. It is almost certainly the bug fixed by commit 9744197c3d7b329590c2be33ad7b17409bd798fe which went into 2.6.27.
Nothing is actually going wrong. It is just an annoying message. If it bothers you, run the command echo 0 > /proc/sys/kernel/hung_task_timeout_secs as the message suggests. NeilBrown -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
