high interrupt rate on ichsmb0

Hello,

I have a system running 13.2 that shows a high interrupt rate on "ichsmb0
16". vmstat -i reports

---
irq16: ichsmb0                  72353386     148839
---

I cannot really find out what is causing this. Unloading the ichsmb module
is possible, but the system reloads it again automatically, still showing
the same issue. I don't see any error messages. Rebooting doesn't help, the
newly booted system shows the same issue. I would think that this wasn't
there some time ago, so there are good chances that it appeared with the
upgrade to 13.2 I did a few days ago.

This is on a Supermicro X11DPH-T mainboard. Any suggestions how to find
out more about the reason for this, and maybe fix it?
