| cjwatson | Hi | 01:05 |
|---|---|---|
| bryce | heya | 01:07 |
| mlankhorst | if realloc crashes, couldn't you try valgrind? | 01:07 |
| cjwatson | FWIW, I'm continuing with the tail-end of the respins; it doesn't lose us that much even if we end up respinning for this | 01:09 |
| cjwatson | And it will let Kubuntu get going with validation | 01:09 |
| mlankhorst | but what exactly is the issue now? I haven't really followed it as I was trying to fall asleep | 01:10 |
| cjwatson | bug 1124660 | 01:11 |
| ubottu | bug 1124660 in xorg (Ubuntu) "Precise 20120213 i386 live session fails in virtualbox" [Undecided,New] https://launchpad.net/bugs/1124660 | 01:11 |
| cjwatson | As I think Sarvatt pasted, my take is that I don't currently see how the /dev/port patch could have changed memory allocation behaviour, and thus there is a tempting working hypothesis that says that this was lurking all along and that it's possible that we've just gone from fatal server error to a realloc crash, in which case who really cares | 01:12 |
| cjwatson | But Sarvatt is right to flag a possible regression and I think we should make sure we understand it | 01:12 |
| Sarvatt | backport X stack + vesa is working fine with the newer libpciaccess on intel, http://paste.ubuntu.com/1647335/ | 01:12 |
| bryce | cjwatson, yes seems plausible | 01:13 |
| cjwatson | sleep> tell me about it, I got three hours last night and I've been up for 17 hours now | 01:13 |
| Sarvatt | i've only been able to reproduce it in virtualbox so far | 01:13 |
| mlankhorst | Sarvatt: what makes you think it's an abi break though? | 01:13 |
| mlankhorst | I don't see anything in the patch that owuld indicate that | 01:13 |
| bryce | mlankhorst, the stacktrace looked like what you might get from an abi break. just a guess though. | 01:14 |
| mlankhorst | meh valgrind it | 01:15 |
| * mlankhorst checks if virtualbox works | 01:15 | |
| mlankhorst | nope, guess ill netboot and do it over nfs on a crappy 100 mbit :/ | 01:16 |
| cjwatson | Isn't the failure specific to vbox hardware? | 01:18 |
| mlankhorst | probably | 01:18 |
| cjwatson | plars might still be around and walkable through it | 01:18 |
| cjwatson | 23:58 * plars -> supper, then back for more iso testing | 01:18 |
| mlankhorst | but i can run it in a virtualbox over netboot | 01:18 |
| cjwatson | that was 80 minutes ago | 01:18 |
| cjwatson | ah | 01:18 |
| mlankhorst | it's also very slow but I'm not really awake anyway | 01:19 |
| Sarvatt | hmm, but vesa works when booting the livecd, its just when you click try ubuntu that there is a crash | 01:20 |
| cjwatson | The effect of "Try Ubuntu" is to fall out of ubiquity-dm and let lightdm start | 01:22 |
| cjwatson | So it'll be tearing down the server and starting a new one after whatever random plumbing wibble happens around there | 01:22 |
| cjwatson | ^- technical term | 01:22 |
| RAOF | Heh | 01:23 |
| * mlankhorst tries hard not to fall asleep | 01:26 | |
| mlankhorst | cd is http://cdimage.ubuntu.com/precise/daily-live/current/precise-desktop-i386.iso ? | 01:26 |
| cjwatson | Yes | 01:26 |
| * RAOF wonders what will happen first: the fibre-to-the-home rollout hitting his house, or that iso downloading. | 01:27 | |
| Sarvatt | RAOF: axel? | 01:29 |
| mlankhorst | great, virtualbox doesn't work on lts kernel | 01:29 |
| RAOF | Sarvatt: ??? | 01:30 |
| Sarvatt | axel http://cdimage.ubuntu.com/precise/daily-live/current/precise-desktop-i386.iso | 01:31 |
| mlankhorst | ugh | 01:31 |
| Sarvatt | axel -n 32 if its slow? :P | 01:31 |
| mlankhorst | fine try 2 from quantal itself | 01:31 |
| mlankhorst | looks like virtualbox hates me today | 01:32 |
| RAOF | Sarvatt: Ah. The "make the server admin hate you" application :) | 01:32 |
| mlankhorst | vbox is only mildly slow | 01:43 |
| mlankhorst | blah | 01:46 |
| mlankhorst | cd panics on me | 01:46 |
| mlankhorst | virtualbox from quantal | 01:48 |
| RAOF | Hm. Seems to work fine in kvm, too. | 01:51 |
| mlankhorst | second try starts normally | 01:53 |
| mlankhorst | I'm just going to pretend I didn't see a kernel panic | 01:53 |
| cjwatson | :) | 01:57 |
| mlankhorst | same thing happening here though | 01:57 |
| cjwatson | The realloc crash? | 02:00 |
| mlankhorst | well hitting failsafe-mode but really too tired to look atm, i dont think its a regression though, just something that wasn't hit before | 02:01 |
| cjwatson | OK; thanks for the investigation, at present I'm minded to not let this block | 02:02 |
| Sarvatt | downgrading libpciaccess just gives me the black screen and [ 206.226] (II) VESA(0): VESA BIOS not detected this "fixed", not even failsafe | 02:02 |
| bryce | cjwatson, thanks. should the issue get mentioned in some release notes maybe? | 02:03 |
| cjwatson | I would welcome an X developer writing an appropriate note in https://wiki.ubuntu.com/PrecisePangolin/ReleaseNotes/CommonInfrastructure | 02:04 |
| mlankhorst | << dlrrp | 02:04 |
| bryce | on it | 02:05 |
| GeoffCh | This sounds like a problem I used to run into sometimes on previous distros, not in a VM but on a couple of different laptops. I found that if I clicked on "Try Ubuntu" it would sometimes hang, but if I closed the window by clicking on (X), I would get back to an X session every time. | 02:07 |
| bryce | Sometimes enters failsafe-x mode when booting into Live Session in virtualbox. (LP: #1124660) | 02:09 |

| bryce | more to say than that? | 02:09 |
| mlankhorst | what if you try libpciaccess from quantal? | 02:10 |
| Sarvatt | bryce: on i386 only, can be worked around by using amd64? | 02:11 |
| bryce | Sarvatt, ok | 02:11 |
| Sarvatt | mlankhorst: trying that now | 02:12 |
| bryce | alrighty, done. | 02:12 |
| Sarvatt | mlankhorst: that works! | 02:13 |
| Sarvatt | http://cgit.freedesktop.org/xorg/lib/libpciaccess/patch/?id=a798395a1bfd9d06d40e2d8d14377a156c94429a ...? | 02:20 |
| cjwatson | bryce: Well, the problem is also that failsafe-X mode doesn't work, AIUI from the bug | 02:21 |
| mlankhorst | Sarvatt: sounds likely | 02:21 |
| Sarvatt | thats it | 02:21 |
| Sarvatt | with that commit added it works again | 02:22 |
| cjwatson | Sounds possibly lucky that amd64 works | 02:22 |
| bryce | cjwatson, ah right | 02:22 |
| cjwatson | OK, let's have that patch for 12.04.3 then, thanks :) | 02:22 |
| Sarvatt | SRU after, if someone installs with updates checked it'll pull it in and work after boot? | 02:23 |
| mlankhorst | or maybe its reallocating SOMEONE ELSE's allocation | 02:23 |
| Sarvatt | alrighty! | 02:23 |
| mlankhorst | ;P | 02:23 |
| cjwatson | Sarvatt: I'm not in much of a panic about virtualbox not working - dailies aren't a terrible option there | 02:23 |
| * Sarvatt nods | 02:23 | |
| cjwatson | The main value is helping our own testers | 02:23 |
| Sarvatt | really sorry for all the trouble here | 02:24 |
| cjwatson | But I think they might actually crucify me if I respun at this point for only that :) | 02:24 |
| cjwatson | Don't worry, it doesn't look like you broke anything | 02:24 |

| mlankhorst | morning | 12:18 |
| user12423 | I have read that ubuntu 12.04.2 comes with kernel 3.5. Will it work with proprietary ati drivers for radeon 4000 series as they are not compatible with quantal? | 16:43 |
| mlankhorst | if you use the old xserver/kernel sure | 16:44 |
| mlankhorst | which is what you keep if you upgrade from 12.04.1 to 12.04.2 | 16:45 |
| user12423 | mlankhorst: just old xorg or kernel too? | 16:45 |
| mlankhorst | the combination old xserver + new kernel is unsupported | 16:46 |
| mlankhorst | it will probably work, but it may set your cat on fire | 16:46 |
| user12423 | mlankhorst: so that means I just have to work with kernel 3.2. Probably but the kittens will extinguish it | 16:48 |
| mlankhorst | lets hope so :) | 16:49 |
| user12423 | mlankhorst: yeah :) | 16:49 |
| user12423 | mlankhorst: amd did a update to its legacy drivers to version 13.1. Do they work with 3.5 and new xorg? | 16:50 |
| starks | mlankhorst, prime helpers have landed in drm-next. | 17:07 |
| mlankhorst | starks: ah, still not that useful | 17:07 |
| starks | needs fencing? | 17:07 |
| mlankhorst | doesn't actually do anything | 17:08 |
| mlankhorst | at least not what I care about | 17:08 |
| starks | can nvidia release a driver against 3.9? | 17:08 |
| mlankhorst | makes me wonder why nvidia cares though | 17:08 |
| mlankhorst | I'm not nvidia | 17:08 |

| tjaalton | what was the metapackage that reverts to the original precise stack? | 20:23 |
| tjaalton | xserver-xorg-lts-precise? | 20:24 |
| tjaalton | that was it | 20:24 |
| mlankhorst | step 4 is unneeded | 20:25 |
| mlankhorst | we use autobind patch for now | 20:26 |
