I had to stop testing Fedora pre-releases until debug is off, because my test machine gets painfully slow already few Fedora releases back.

I am not sure whether there was any decision to build both kernels (w and wo debug) for test releases and let the user decide, but I can not use the kernel with debug enabled.

It goes from 45 to about 98 in a matter of 10 seconds or so. I should probably add here couple comments - the heat of CPU at least on my T61 is heavily influenced by BIOS settings - if there is not enabled maximum performance and BIOS is allowed to handle thermal peace and quietness and throttling, then CPU is kept within 60 degrees. However when all such options are turned off - it goes easily to 95 degrees - but not in matter of seconds - fan would have to be kept off for such fast temperature increase - it takes like minutes to climb so high with default 'auto' fan settings. Since some time - I'm happy user of slightly modified 'thinkfan' tool to keep my laptop slightly warmer and mostly completely quite. Modification is for usage of 'disengaged' level - thus when my CPU goes over the 70 degrees (i.e. kernel compilation, stress -c4,...) this highest fan speed keeps the CPU around ~74 degrees - no way to go higher. So I'd suggest to check whether 'level disengaged' is fast enough to avoid overheating (check for 'options thinkpad_acpi fan_control=1 experimental=1') If you are still able to burn your CPU quickly - then you cooling does not work properly and should be cleaned (or replaced).

Not sure if other laptops are having same issue, but could be because debugging turned on in the kernels at present, as well as that making it slow, also making X or some other resource using lot of CPU to compensate for it. Might try booting with kernel as slub_debug=- and see if that helps make any different. If it does, then the next kernel build I think is suppose to have debugging turned off and that might help.

Is anyone else experiencing this issue? Any tips for digging out the root cause on this? One, I'd blame your laptop manufacturer, as any hardware which can't cope with being run at full capacity for a reasonable period is badly designed hardware. But that's not going to get you very far. =) (to mitigate, you can get one of those cooling pads for laptops - they look dumb, but they actually work. I had a similar laptop once that would overheat-protect-shutdown when building kernels; a cooling pad solved that problem. Or you can just try and clean out the externally-accessible heatsinks a bit, that can help.) Tracker shouldn't eat 100% cpu time for really extended periods, so if it's doing this for more than, say, an hour, that may well be a bug in tracker. You might also want to check if lldpad is installed, and if so, remove it or upgrade it to fix https://bugzilla.redhat.com/show_bug.cgi?id=701943 , which could be contributing to the problem (the update is linked in the bug). -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
Re: Laptop overheating with F 16
Yeah the argument can always be made that it is a HW issue. In this case, running under windows I run into no thermal issues. As well, running under F 15 created no thermal issues. I will give a shot at disabling debugging to see what happens but this feels more deep seated than that to me. However, my clairvoyance is often in doubt. -Erinn -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
Re: Laptop overheating with F 16
Adam, I suppose it could be the manufacturers fault, I have had this Lenovo ThinkPad T510 for a long time and never had any issues with it. As well, this thing isn't even on my lap it is in a dock with a pretty decent ventilation setup. I know we hear this all the time in this business, but it used to work just fine. Perhaps it is hardware failing, but why then would windows never display any thermal issues, perhaps it is really good at hiding it. Here is the logs from the first few minutes of the system being up: [ 69.065721] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9053, limit 9000 [ 74.055719] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9739, limit 9000 [ 76.346477] nautilus used greatest stack depth: 2400 bytes left [ 94.015696] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9110, limit 9000 [ 96.742668] CPU3: Core temperature above threshold, cpu clock throttled (total events = 1) [ 96.742676] CPU2: Core temperature above threshold, cpu clock throttled (total events = 1) [ 96.743699] CPU2: Core temperature/speed normal [ 96.743701] CPU3: Core temperature/speed normal [ 99.005684] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9687, limit 9000 [ 103.995677] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9367, limit 9000 [ 108.985716] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9021, limit 9000 [ 113.975683] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9598, limit 9000 [ 133.935783] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9350, limit 9000 [ 138.925640] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9309, limit 9000 [ 158.885623] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9638, limit 9000 [ 163.875602] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9113, limit 9000 [ 193.815559] intel ips :00:1f.6: MCP limit exceeded: Avg temp 10074, limit 9000 [ 203.795558] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9029, limit 9000 [ 208.785623] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9704, limit 9000 [ 218.765551] intel ips :00:1f.6: MCP limit exceeded: Avg temp 9386, limit 9000 [ 223.755543] intel ips :00:1f.6: MCP limit exceeded: Avg temp 10147, limit 9000 [ 238.725550] intel ips :00:1f.6: MCP limit exceeded: Avg temp 10052, limit 9000 Even by my standards this seems a bit in excess. The fan is working and throttling up and down as would seem to be required. As I said cooling isn't really an issue given the docking. Most thing point me back to F 16. Like I said this machine has never shut down on me because of a thermal event, since upgrading to Fedora 16 it has happened a number of times (4-5 I think). As well kernel debugging was disabled to no avail, though the machine is a bit more responsive now. -Erinn -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

I ran stress -c 5 (I have 4 cores with HT) on the laptop and was able to generate the CPU thermal events under F 16. So I then ran prime95 in windows for about an hour, didn't get anything in the logs, though I don't pretend to understand windows logging structure or to even say mine is set up correctly. So I then switched to booting F 15 from a rescue disk, and chrooting into my F 16 install and running stress -c 5 again (basically a long way around to booting an older kernel), and I was unable to generate the CPU thermal events. I doubt this is an apples to apples comparison, but it is about as close as I can get with what I know. Is it possible the F 16 is just logging more information and that is why I am seeing this error? Like I said never saw this with F 15, you believe it is HW, I don't buy it yet, so is there something else that could explain it? yeah, that does point to something else, which is interesting: it's hard to see offhand how F16 could be running a lot hotter than F15 or Windows assuming you ran up a heavy load on all of them. I suppose the graphics card could be running hotter in F16 for some reason and that'd be pushing it over the edge. AIUI, the actual overheat cutoff levels and the overheat shutdown mechanism itself are implemented in the system firmware (BIOS) and Linux just passes along the messages, so it's not that these overheat levels are different in F16, or exist in F16 but don't exist in F15 or Windows, or anything like that. I'm pretty sure it must actually be the case that your system really is running physically hotter in F16. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

If you think it's F16, try running from a live cd of F14/15 for a while to be sure? And you can also manually force the fan to run at max speed, see if that helps? (modprobe thinkpad_acpi fan_control=1 needed, I think) Well folks, thank you all so much for your time and energy. Adam, thanks for your patience. Looks like this is a hardware issue, I don't know why it didn't crop up before when I was load testing F 15 and Windows, but after jumping into Windows to try and get the temperatures, as suggested, for a point of comparison the system over heated and shut down. In fact it did it twice in a row, so that is more than enough confirmation for me, I will be talking with Lenovo to get new hardware. I will also close up the bug report I filed. Thanks again for your patience and the information, I learned a lot during this process. -Erinn -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

It can certainly help. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | identi.ca: adamwfedora http://www.happyassassin.net -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test

Funnily I went into the same problem on F15 and that happened before and after I replaced the fan. It's also a Thinkpad, but older generation (T60). I regularly get shut down because of excessive heat or can't reboot because of it. Never ever happened before F15 (I assumed it was a hardware problem). I'll re-read the thread and see if I can get useful metrics. Thanks. Fred -- test mailing list test@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
