| hans109h_ | Re: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1313981 what can I do to test why the mainline kernel wouldn't load? | 03:06 |

| mlankhorst | regression testing? :P | 07:05 |
| Chainsaw | Good morning. Can you let me know if you have sufficient information on https://bugs.launchpad.net/ubuntu/+source/linux-lts-saucy/+bug/1314764 please. | 08:17 |
| ubot2 | Launchpad bug 1314764 in linux-lts-saucy (Ubuntu) "[Fujitsu Lifebook E744/E754] i8042 without psmouse means no keyboard at decryption prompt" [Undecided,Confirmed] | 08:17 |
| apw | Chainsaw, looks pretty clear, it sounds like a bug in initramfs-tools not putting that module in | 08:33 |
| Chainsaw | apw: Yes, either putting it in the initramfs by default or building it into the kernel proper will solve it. | 08:34 |
| Chainsaw | apw: We will make the change in the initial build, but I work for a company of shall we say.... power users. | 08:34 |
| Chainsaw | apw: They want to install their own laptops, and then get confused and annoyed when it "don't work". | 08:34 |
| apw | yeah, they tend to do that indeed :) | 08:34 |
| apw | if initramfs-tools wasn't an utter mess this would be a trivial fix i am sure | 08:35 |
| apw | hans109h_ (N,BFTL), it looks like the device probe has failed; details in your bug | 09:39 |
| apw | Chainsaw (N,BFTL), I think i have fixed this in the packages I have pointed to in your bug, if you could test those and let us know on the bug pls. | 11:02 |
| soren | Do you guys run any benchmarks to see how kernel updates affect performance? | 11:36 |
| apw | there was a plan for that, and some work done, what sort of benchmarks were you looking at | 11:39 |
| soren | I was actually looking for inspiration in terms of picking some good benchmarks :) | 11:41 |
| apw | i guess it depends what you are trying to check on | 11:42 |
| soren | My intent is to try to compare various cloud providers. Nothing more specific than that. | 11:43 |
| soren | I imagine I want to test disk I/O, CPU speed, memory I/O and other stuff. | 11:44 |
| soren | ...and if you guys already had a ready-to-go test suite, that'd just make my life easier. | 11:44 |
| apw | stress is good for memory/cpu, xfstest is good for filesystems, but no i don't think we have anything specifici | 11:45 |
| soren | No worries. Thanks. | 11:48 |
| cking | soren, stress-ng in my ppa:white is also handy | 11:53 |
| soren | cking: Cool, thanks! | 11:54 |
| cking | soren, i've tried out fs tools such as bonnie++, tiobench but they all have their pros and cons | 11:55 |
| cking | iozone too | 11:56 |
| soren | cking: Phoronix has this huge test suite, but I get the impression that it's not very popular for some reason. | 11:57 |
| cking | soren, one needs to run a specific test multiple times and calculate std.dev. correctly | 11:58 |
| rtg | I'd sure like to upload 3.15-rc3 but I'm gonna have to figure out my resume issue first. | 14:20 |
| rtg | apw, are you having any resume issues on your kit ? | 14:40 |
| apw | rtg, with 3.15 or with 3.13 ? | 14:41 |
| apw | though ... not so far is my answer either way | 14:41 |
| rtg | 3.15-rc3 | 14:41 |
| apw | rtg, just did two s/r on my lappy her with 3.15-rc3 and nothing bad for me | 14:43 |
| rtg | grumble | 14:43 |
| trippeh | ya, -rc3 works ok here too. for suspend/resume. | 14:51 |
| trippeh | not tried to disk however. | 14:51 |
| xnox | smb: or rtg: (not sure who deals with xen) is grub1 still needed for xen in ubuntu? | 15:19 |
| xnox | or maybe apw ? ^ | 15:19 |
| rtg | xnox, it would be smb, but I think he's out today. | 15:20 |
| apw | xnox, yeah it'd be smb, he is out till monday i think, and ... i don't personally know the answer, hallyn might | 15:21 |
| xnox | right, may day mayhem. | 15:21 |
| hallyn | sorry i have no idea. zul might :) | 15:21 |
| zul | xnox: it shouldnt | 15:30 |
| rtg | apw, ogasawara: www.decadent.org.uk/ben/tmp/linux-release-dates.svg - 3.17 might be really close. | 17:13 |
| ogasawara | rtg: yah, I was looking at http://phb-crystal-ball.org/ too | 17:14 |
| rtg | hmm, they differ by a month | 17:14 |
| rtg | oh, maybe not quite that much | 17:15 |
| apw | rtg, well it depends where the labelled line is, is that jan1 or jan31 | 17:15 |
| ogasawara | rtg: I think what we've been saying that at the least it'll be 3.16 is the safe answer | 17:15 |
| apw | rtg, otherwise 3.17 is oct 16 or so by the graph | 17:15 |
| apw | which is release day | 17:15 |
| rtg | apw, yup, I agree | 17:15 |
| ogasawara | rtg: if we did 3.17, it would certainly go out the door with a later -rc | 17:16 |
| rtg | ogasawara, which we've done before | 17:16 |
| apw | we normally like to get a .N or two on though | 17:16 |
| ogasawara | rtg: I guess it somewhat depends what we might be getting in 3.17 and if it's worth it | 17:16 |
| apw | given it goes back into the lts, is there enough time before the point release to get it lts stable | 17:16 |
| rtg | I guess we won't know until we get there | 17:17 |
| ogasawara | we'd have another 3mo before it'd go back into trusty | 17:17 |
| ogasawara | which really means like 2mo to get it lts stable | 17:17 |
| apw | yeah, so i guess we get .6 by then not toooo bad | 17:18 |
| sconklin | arges: to be clear, you're asking me to build my own kernel with lockdep debugging and test that? | 18:05 |
| arges | sconklin: ugh sorry | 18:17 |
| arges | sconklin: i forgot to post the link | 18:17 |
| arges | sconklin: ok updated | 18:17 |
