| memeka | hi, my system hangs on reboot (but not on shutdown) and i need to plug off/plug back the power to make it respond - what's the best way to debug the kernel - find out exactly where the reboot code is? | 04:42 |
|---|---|---|
| apw | teward, yep thermald is one of ours ... | 07:52 |
| apw | memeka (N,BFTL), there are a number of ways to skin the reboot cat, and normally you would try them all to see which works and add a quirk to select that one | 07:53 |

| teward | apw: still around? (sorry i wasn't around at 03:52 local) | 15:16 |
| teward | apw: or kernel team, before I poke hggdh or the quality list admins to silence something that should probably be squished, https://lists.ubuntu.com/archives/ubuntu-quality/2016-July/006585.html may be of interest, regarding why something was fix released for wily but didn't fix things (and possibly didn't fix for Trusty) | 15:17 |
| teward | wrt bug #1543046 | 15:18 |
| ubot5 | bug 1543046 in thermald (Ubuntu Wily) "thermald spamming kernel log when updating powercap RAPL powerlimit" [High,Fix released] https://launchpad.net/bugs/1543046 | 15:18 |
| apw | cking, ^ this is a thermald thing that is marked fixed but seemingly not so | 15:19 |
| teward | apw: no confirmation of still existing for Trusty | 15:19 |
| teward | and i need guidance for the Wily side | 15:19 |
| teward | i.e. "Would it be fixed before EOL and would it do any good to change the bug status for wily" | 15:19 |
| teward | asking as bugcontrol not QA :P | 15:19 |
| teward | s/bugcontrol/bug triage/ | 15:20 |
| cking | apw, ok, I'll look at it on monday, although I'm surprised by this :-/ | 15:20 |
| teward | cking: without taking a look at it, can you give me a best guess as to whether this close to Wily EOL we actually care about getting this fixed before it EOLs? | 15:22 |
| teward | I can understand it needs poked for Trusty if it still exists, I don't see justification for Wily which dies off in 20 days | 15:22 |
| teward | (as a bug triager, not a kernel guy) | 15:22 |
| rtg | cking, plus we're aren't gonna updatethe kernel anymore | 15:22 |
| cking | teward, well, I know the code well, so it's trivial for me to eyeball and I can turn it around on monday quite easily as long as nothing higher priority hits me over the weekend | 15:23 |
| teward | ack | 15:23 |
| cking | when is wily EOL now? | 15:23 |
| teward | 28th | 15:23 |
| teward | message went out from infinity yesterday | 15:23 |
| teward | over the announce lists | 15:23 |
| cking | ok, I'll see what I can to monday, I was pretty sure I tested this on my x220, but oh well, I screwed it up I guess | 15:24 |
| teward | cking: i'll reply saying it's in the Kernel Team's hands now, and to stop the bickering on the QA list | 15:24 |
| teward | is there a kernel ML you want me to CC on with that reply? | 15:24 |
| cking | teward, I'd prefer for me to just update the bug report | 15:25 |
| teward | ack | 15:25 |
| teward | cking: i'll leave it be and say it's back in the Kernel team's hands, and to leave it be until such time one of the team's members reply to the bug. | 15:25 |
| teward | it's still needing an anti-drama squish. | 15:25 |
| teward | (on the quality ml) | 15:25 |
| cking | it's not going to kill anyone, it's been like tyhat for a while without much drama | 15:27 |
| teward | indeed. there's drama between two people on the ML | 15:27 |
| cking | they need more beer | 15:27 |
| teward | and *that* needs squished (it's no longer just a report of 'marked fixed but not fixed') | 15:27 |
| rtg | they need to upgrade to xenial | 15:27 |
| cking | +1 rtg | 15:27 |
| teward | rtg: that's what i said in my reply to the thread heh | 15:32 |
| teward | but, alas, end users will be end users, so... :: | 15:32 |
| teward | :P * | 15:32 |
| hggdh | teward: OTOH, php4fan has just earned moderation on the ML. | 15:47 |
| teward | hggdh: oh joy | 15:47 |
| hggdh | I still think php4fan and Teo Teo to be one and the same | 15:47 |
| teward | hggdh: this wouldn't be the same guy from before would it? (I recently pruned all my mailing list messages from my main inbox, CBA to pull up the archive) | 15:47 |
| teward | ahh that's the one I was thinking about | 15:48 |
| teward | hggdh: funny story, I was going to ping you on it privately, too, and ask for some higher power to be called forth, but lunch was calling first :P | 15:48 |
| teward | thanks for the FYI | 15:48 |
| hggdh | yw. Pity, though. This person uses Wily for his "production", and still does not understand the difference between LTS and interim | 15:49 |
| teward | hggdh: hey, that's 50% of the Ask Ubuntu people, it's why I started posting the EOL notices. | 15:50 |
| teward | so people aren't all "WHY THE [censored] DID MY POST GET CLOSED WHAT IS EOL WHAT IS THIS ..." | 15:50 |
| teward | *rolls eyes* | 15:50 |
| hggdh | good idea. | 15:51 |
| cking | teward, I've prepared a fix, I'll get the user to test it from a PPA and upload it once they verify it works | 16:08 |
| teward | cking: ack | 16:09 |
| memguy | curious does anybody know what db000000-db7fffff : RAM buffer i have tried to read from it and i cann't do that i just curious on what it is used for some kind of buffer cache or something but don't understand it (how it is used,why , and what is using it) | 18:59 |
| mjg59 | memguy: If a region of RAM doesn't end on a 64MB boundary and there's nothing else allocated there, the kernel reserves the space to reduce the probability that there's actual RAM there being used by the firmware | 19:03 |
| mjg59 | Otherwise you might map an mmio device on top of it | 19:03 |
| memguy | wait so what happens if the region ends on 64MB boundry | 19:06 |
| memguy | i guess i don't see the point of it and why they named if ram buffer | 19:06 |
| memguy | curious is there a cpu feature or flag that has something to do with cpu temperature because i have seen /dev/temperature or other devices and read into it a little bit. Can processors detect there temperature there running at like they can with voltage and frequency settings thru power management | 20:24 |
| memguy | i am curious if there is a /proc/cpuinfo flag name for this which would control the setting range of what the cpu temperature range it will run at before halting to resume that range . would be a cool feature to beable to turn off and on | 20:26 |
| memguy | in conjunction with p-state and t-state and c-state | 20:27 |
| memguy | I guess alot of this can be obtained from ACPI but was curious on if there is a flag and dedicated cpu feature for all this processor temperature,freq, cpu voltage/current | 20:39 |
| memguy | spped | 20:39 |
