Ever since i upgraded to Sid and longterm kernel 4.1.12 i have been having this weird problem. temp2_input, temp3_input, temp4_input and temp5_input which give the CPU core temperatures, keep switching between /sys/class/hwmon/hwmon1/ and /sys/class/hwmon/hwmon2/ after every shutdown. I am forced to edit my conky.conf accordingly after every cold start to have them displayed correctly in my Conky. Other than that everything is in tip-top shape. This is my most stable, trouble-free and snappy Debian configuration to date. Gkrellm is unaffected by this, btw. Betcha this is a new one even for the seniors here, to me it's like voodoo..
Edit: Seriously people, this is really happening..
