Yes there is an IPMI card on these boards. I'm not sure if they use I2C
but I think that would make sense. We are not actively querying values
via the IPMI card, however it does it by itself.

It seems bursty, e.g. like many times within a second and then its
silent for some time, e.g. one node has this disribution:
n0047:~# dmesg | egrep '(i801_smbus|w83793)' | cut -d. -f 1 | \
tr -d '[' | sort -n | uniq -c
1 8

second column shows seconds since last boot.
Does this help, or shall I do it on every node and think about a way to
show this in 2d?
