[Bug 754783] New: nepomuk-indexer causes Lenovo Thinkpad X201 to shutdown for termal protection (overheat)
https://bugzilla.novell.com/show_bug.cgi?id=754783 https://bugzilla.novell.com/show_bug.cgi?id=754783#c0 Summary: nepomuk-indexer causes Lenovo Thinkpad X201 to shutdown for termal protection (overheat) Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: openSUSE 12.1 Status: NEW Severity: Major Priority: P5 - None Component: Mobile Devices AssignedTo: mobile-bugs@forge.provo.novell.com ReportedBy: stakanov@freenet.de QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:11.0) Gecko/20100101 Firefox/11.0 I have a lenovo Thinkpad X201. The machine has 8 GB ram. I did attribute 1 GB to nepomuk indexing service to ease the work of the program. The system with nepomuk-indexer running (showing in top 100% CPU time), does not slow down operations but causes the machine gradually to overheat. It eventually then shuts down for having reached the thermal protection level. If you switch off desktop indexing, the overheats stops and the machine turns to normal. This machine did never heat up before under linux (running 11.1 before). This happens with the machine on power plug, with our without battery loading, with our without ultrabase support. The culprit is clearly the running indexing process. Reproducible: Always Steps to Reproduce: 1.Take a X201 Thinkpad notebook with 8 GB ram and 64 bit openSUSE 12.1. Activate desktop search and attribute 1 GB of memory to the indexer. 2.start the machine in normal operation, indexer will run. 3.machine will gradually overheat (you can hear the ventilator) and finally shutdown in thermal emergency. Actual Results: machine does overheat Expected Results: the desktop should be indexing without problems giving the reckoning power and the architecture / amount of memory available. The critical temperature should not be reached on a healthy system at normal room temperature. Nepomuk / strigi should take notice of thermal load in mobile devices. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The reference is to: https://bugzilla.redhat.com/show_bug.cgi?id=675433 This because I found regular entries in /var/log/messages like: [ 6646.665328] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 35143, limit 35000 With strigi this is a constant. The packman rpm causes overheat in about 10 minutes. The openSUSE one causes shutdown randomly. Often tempearture rise to 99 C (at 100 shutdown) and the average temperature machine is of 68 some days 83 C with normal system operation on a day with 20 C room temperature. I think this will be a troubled summer. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The problem seems to be with the intel_ips module so I'm currently testing without having it loaded. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Seems to be a combination of nepomuk workload (bug) and intel_ips or kernel. In 12.2 the problem seems to be solved in the sense that overheating shutdown does not take place any more. Although the machine works still at quite high temperature levels. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
