Dell Precision 360 dies under high load
Last modified: 2015-03-04 20:17:22 EST
Description of problem: Each of my 3 Dell Precision 360 die under high load. They just switch off at 54°C processor temperature, without shutting down. I tried with Knoppix 4, the problem does not exist here. Version-Release number of selected component (if applicable): How reproducible: always within 20 minutes, in 90% of the cases in 5 minutes Steps to Reproduce: 1. while true; do i=5; done 2. try to wait 20 minutes 3. Actual results: System dies Expected results: System stays alive Additional info:
It sounds like your hitting some form of thermal trip in the processor, yes? 54C is 129F, which is pretty hot... No messsages in dmesg leading up to this? The CPU fan is doing alright?
I tried on 3 equal computers and exchanged all fans (one). There is no related message in /var/log/messages. The same problem occurs on FC 4.
Sometimes the system goes down at 52°C, sometimes at 54°C, sometimes at 53°C. There is a message in the Bios log about a thermal shutdown.
Distro Error occurs Can start /etc/init.d/lm_sensors Knoppix 4 no no SLES 9 no no SUSE 9.3 no no Fedora 4 yes yes Fedora 5 yes yes SUSE 10 yes yes SUSE 10.1 yes yes SLES 10 yes yes
I wrote an Operating System stub as described under http://www.staerk.de/thorsten/index.php/How_to_program_your_own_OS That OS sends the processor into an endless loop. Running my Precision 360 with it, it never powers off. Note that the processor is running in real mode here.
Deleting /etc/sensors.conf and /etc/sysconfig/lm_sensors resolved the problem under SUSE.
Have you tried disabling lm-sensors on Fedora, too? Read ya, Phil
On a fresh installation of FC5 without lm-sensors, the problem does not occur. I would recommend to add a big warning when installing lm-sensors, or to take it away from the distribution completely.
I found out, the "set" commands in the /etc/sensors.conf file cause that problem - outcommenting some of them resolved the error. With FC5, sensors is not functional, therefore no problems. Can we change this in the distribution ?
Do you still get the problem with updated lm_sensors packages in FC6 or Fedora Devel? Read ya, Phil

Since there have not been any updates to the report since thirty (30) days or more since we requested additional information, we're assuming the problem is either no longer present in the current Fedora release, or that there is no longer any interest in tracking the problem. Setting status to "INSUFFICIENT_DATA".
