I was not aware of replying style of this mailing list and I clicked 'reply' instead of "reply all". you would not see an error, but something like ACPI Warning: 0x000000000000f040-____0x000000000000f05f SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20130517/utaddress-251) ACPI: This conflict may cause random problems and system instability ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver Unfortunately workstation Raphson died this week. It was running a long process using MKL and ATLAS math libraries and when I got in the office in the morning it was shutdown. Push power button: nothing happens. Unplug and plug power cable: the fans work for a few seconds and then stop. I was taken to the technical assistance. Let's assume you don't see that. Next question is if your system supports IPMI. If it does, there is a slight chance that the IPMI controller accesses the SMBUs, causing an access conflict. IPMI is an Intelligent Platform Management Interface, right? How can I check if my sistem supports IPMI? Our workstations are using Ubuntu and Kubuntu 12.04 LTS. I don't remember if I did install such interface. You'll find that information in the board specification. The output from sensors-detect below also shows you that the board supports IPMI. Furthermore, the Intel server board specification states that IPMI monitors the temperature and voltage sensors on the board. So if Raphson uses the same board, the most likely explanation for your problem is that IPMI and the jc42 driver try to access the DIMM temperature sensors at the same time. This would expmain both the read errors and the occassional resets (if IPMI resets the board if it happens and it reads a bad/high temperature). Guenter Thank you for your clarification, Guenter. Kalman and Gauss have the same motherboard that Raphson. I'll uninstall lm-sensors and use ipmitools to monitor temperature instead, as Jean Delvare pointed. Do you think that the conflict between IPMI and lm-sensors could also explain the last Raphson's failure? It worked for about one month at full load and suddenly shut down and never turned on again.
That is really quite unlikely. Of course, it is theoretically possible that this could happen, for example if there is a badly managed power controller chip involved. I don't think that is the case here, though. After all, we are talking about access to temperature sensor chips, not power controllers.
