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
      1 25241
      1 26501
      1 53262
      1 123160
      1 132928
    196 137025
      1 144900
      1 156875
      1 198766
      1 229545
      1 266396
      1 280566
      1 285294
      1 286873
      1 298844
      1 312390
      1 318375
      1 337578
     12 367501
      1 380728
      1 422294
      1 433634
      1 444343

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?

Cheers

Carsten
