[01:55] [7341824.537568] ifquery[183]: segfault at 1 ip 00000000004031c8 sp 00007ffc76037c10 error 4 in ifup[400000+d000] [01:55] oops ? :-) [01:55] every boot. interesting. [09:28] trippeh, looks like a bug in ifquery/ifup to me worth a bug i am sure [09:31] * ogra_ sighs ... when did we silently switch to intel_pstate ? [09:32] 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 ) [10:10] * ogra_ files bug 1460399 [10:10] bug 1460399 in linux (Ubuntu) "ivybridge system gets completely unusable after upgrade to vivid thanks to defaulting to immature intel_pstate driver" [Undecided,New] https://launchpad.net/bugs/1460399 [11:49] ogra_, do you have thermald installed as i believe that is meant to be programming those behaviours [11:51] apw, dumping to 166 ot 133MHz is a thermald thing ? [11:51] *or [11:51] (under full load) [11:52] it stopped doing that when i switched back to ondemand ... [11:52] probably pstate enables the turbo states, making it run too hot for your cooling and crashing into thermal throttling [11:54] well, the point is that it didnt manage to get the heat low enough and the BIOS emergency shutdown kicked in every 10-15min [11:55] the system behaves properly after switching back to cpufreq [11:55] (without making any other changes) [11:56] trippeh, thermald does indeed allow turbo and other things, it should of course also not make your machine explode too [11:56] ogra_, using pstat_idle is the recommneded option on these pieces of h/w so i am supprised of your experience [11:56] ogra_, anyhow i've added cking to the thing becuase he did all the work on that back in the day [11:57] (recommended by Intel, ...) [11:57] inte_pstate has been working fine on my hardware, fwiw :) [11:57] 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] even the tiny cooling challenged ultrabooks [11:58] currently i'm fine ... once someone wants to debug it during the week i'm happy to collect data [11:59] after all it got me to clean up 100 of my 150 constantly open firefox tabs ... so it had it's good sides ;) [12:02] ogra_, yeah i'll poke cking monday and see what he thinks [12:03] i only found an older bug from infinity who seemed to have the same issue but in another release [12:03] trippeh, yeah same here, i have a shitey ulrabook [sic] and it is also fine [12:03] bug 1188647 [12:03] bug 1188647 in linux (Ubuntu) "Please change intel_pstate default to disable" [High,Fix released] https://launchpad.net/bugs/1188647 [12:03] 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 [12:04] ah [12:04] thermald is quite noisy in syslog btw [12:04] 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] yeah we ought to look at that, much of that thermal stuff is whiney [12:04] yeah, i noticed :) [12:05] if you could add your thermald logs for the bad period (if you cna identify them) they may be valuable [12:05] i'll look them up [12:18] thanks === swordsmanz is now known as blelladonna === blelladonna is now known as sowrdsmanz === sowrdsmanz is now known as swordsmanz [17:53] 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] 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
