|---|---|---|
| trippeh | oops ? :-) | 01:55 |
| trippeh | every boot. interesting. | 01:55 |
| apw | trippeh, looks like a bug in ifquery/ifup to me worth a bug i am sure | 09:28 |
| * ogra_ sighs ... when did we silently switch to intel_pstate ? | 09:31 | |
| ogra_ | totally trashed my update to vivid (cores switching to 133 MHz while the system is under full load, core temps constantly between 85 and 90°C ) | 09:32 |
| * ogra_ files bug 1460399 | 10:10 | |

| apw | ogra_, do you have thermald installed as i believe that is meant to be programming those behaviours | 11:49 |
| ogra_ | apw, dumping to 166 ot 133MHz is a thermald thing ? | 11:51 |
| ogra_ | *or | 11:51 |
| ogra_ | (under full load) | 11:51 |
| ogra_ | it stopped doing that when i switched back to ondemand ... | 11:52 |
| trippeh | probably pstate enables the turbo states, making it run too hot for your cooling and crashing into thermal throttling | 11:52 |
| ogra_ | well, the point is that it didnt manage to get the heat low enough and the BIOS emergency shutdown kicked in every 10-15min | 11:54 |
| ogra_ | the system behaves properly after switching back to cpufreq | 11:55 |
| ogra_ | (without making any other changes) | 11:55 |
| apw | trippeh, thermald does indeed allow turbo and other things, it should of course also not make your machine explode too | 11:56 |
| apw | ogra_, using pstat_idle is the recommneded option on these pieces of h/w so i am supprised of your experience | 11:56 |
| apw | ogra_, anyhow i've added cking to the thing becuase he did all the work on that back in the day | 11:56 |
| apw | (recommended by Intel, ...) | 11:57 |
| trippeh | inte_pstate has been working fine on my hardware, fwiw :) | 11:57 |
| ogra_ | well, it diidnt help that i wasted 3h into trying to find out why X was so slow ... debugging graphics stuff :P the system really felt like i'm running something even sub-vesa ... | 11:57 |
| trippeh | even the tiny cooling challenged ultrabooks | 11:57 |
| ogra_ | currently i'm fine ... once someone wants to debug it during the week i'm happy to collect data | 11:58 |
| ogra_ | after all it got me to clean up 100 of my 150 constantly open firefox tabs ... so it had it's good sides ;) | 11:59 |
| apw | ogra_, yeah i'll poke cking monday and see what he thinks | 12:02 |
| ogra_ | i only found an older bug from infinity who seemed to have the same issue but in another release | 12:03 |
| apw | trippeh, yeah same here, i have a shitey ulrabook [sic] and it is also fine | 12:03 |
| ogra_ | bug 1188647 | 12:03 |
| ubot5 | bug 1188647 in linux (Ubuntu) "Please change intel_pstate default to disable" [High,Fix released] https://launchpad.net/bugs/1188647 | 12:03 |
| apw | ogra_, yeah and that was before we had thermald paired with it, the kernel bits are useless without hte daemon, and it wasnt packaged then | 12:03 |
| ogra_ | ah | 12:04 |
| ogra_ | thermald is quite noisy in syslog btw | 12:04 |
| apw | which is why i was trying to find out if you have thermald installed and if when in pstate it was running because that is mean to be "the way it works" | 12:04 |
| apw | yeah we ought to look at that, much of that thermal stuff is whiney | 12:04 |
| ogra_ | yeah, i noticed :) | 12:04 |
| apw | if you could add your thermald logs for the bad period (if you cna identify them) they may be valuable | 12:05 |
| ogra_ | i'll look them up | 12:05 |
| apw | thanks | 12:18 |

| bigdissaved | Morning, I am wondering what how I can recomend a kernel driver be added to the dist? It is for the rtl8812AU AC 1200 wireless chip. I have it working on my system, but it is very anoying that I have to recompile and install it every kernel/system update. It is in my garage, and wifi is the only connection that it has. | 17:53 |
| bigdissaved | https://github.com/abperiasamy/rtl8812AU_8821AU_linux this is the source code tree that I am using, and it works flawlesly for my self with 15.04 and 14.04.2 | 17:53 |
