Hi all,

on Supermicro PDMSL-LN2+ boards there is a w83793 chip which seems to
work fine, however, it seems we are hitting quite a few error messages
and I don't know how to get rid off them cleanly

typical messages are:

Google only shows me lots of references to the Linux kernel, but that
does not really help me much right now.

System is running pretty recent 2.6.27 kernel and lm-sensors 3.0.2.

Any hint how i can get rid off these?

Cheers and thanks a lot in advance

Carsten
