You have been subscribed to a public bug: I'm not sure how much of this is rsync or something else in my system. I can reliably trigger this using rsync to transfer files from one drive to another drive on my computer. the source is ssd and destination is mdadm raid 1 partition. will attach syslog messages. after it is triggered, the the system becomes unresponsive and requires a hard reboot. running rysnc as user, no special privileges.
