Hi Olavo,

SHORT STORY:
The workstation suddenly shuts down, usually when performing intensive
computation. Workaround: comment line jc42 at /etc/modules apparently
solves the problem.

On such workstations it is common to have IPMI, possibly even with a
BMC for remote management. In that case it is possible that IPMI and
lm-sensors conflict, as they try to access the same hardware without
synchronization. This would explain the SMBus errors.

If you (or the BMC) are using IPMI, you can't use lm-sensors. Use
"ipmitool sensor" (or a similar command for other IPMI tools) instead.

Hi Jean,
Thanks for replying.
Sorry for the ignorance, but I have just googled for BMC and IPMI to
discover it is a Baseboard Management Controller and a Intelligent Platform
Management Interface. :-). I am the administrator of Raphson workstation
and other phd students are the administrators of Gauss and Kalman
workstations.
So I guess we don't have a BMC or a IPMI installed on our systems.



Nothing you can install; it is either there or it isn't. This is a board feature,
not a software feature.
