This started in late 2013, a month or two after installing Nvidia GTX 760 (and new PSU) --- I reported system hang from sensors command to lm-sensors on Jan 20, 2014. I was avoiding the sensors command since Jan 20 but something used it (me? I don't recall. ipmi?) (as reported in kern.log: blocked for more than 120 seconds.) and it was hanging and the system hung up totally last night, February 16. Found Guenter's January advice (impi conflicts with other hardware monitoring) and since I am not using ipmi I commented out ipmi-si from /etc/modules and rebooted today. lsmod shows no ipmi now. synaptic does not show any ipmi stuff installed. Hopefully the hangs will no longer happen. Thanks. My fault for not finding Guenter's advice sooner.
