| osmosis | hi | 05:56 |
| osmosis | cool man, well let me know if there is anything I can do. Im willing do learn stuff if needed. | 06:09 |
| osmosis | the xen kernel on gutsy amd64 isnt recognized as a valid kernel by grub. | 06:09 |
| rtg__ | osmosis: zul is the xen master. | 06:12 |
| zul | rtg__: im talking to him about it already ;) | 06:12 |
| osmosis | rtg__: yah, but he says "that grub error has to do with the meta package which something i dont have control over" | 06:13 |
| zul | actually its probably update-grub that is erroring out | 06:14 |
| osmosis | zul: true, but even when I manually put the kernel into grub... thats when I get the error 13 on boot...invalid executable. | 06:14 |
| osmosis | zul: update-grub just doesnt put it in the menu.lst, probably can tell its not valid. | 06:14 |
| zul | ok intresting | 06:14 |
| bdmurray | rtg__: Should I bring any last minute kernel bugs to your attention? | 06:17 |

| BenC | ScottK: then we can't put a fix in yet :) | 07:59 |

| BenC | ScottK: it's possible, but all depends on timing and severity | 08:00 |

| pkern | Is there something speaking against a SLAB kernel flavour apart from the fact that it may be too late? | 11:32 |
| amitk | pkern: buggy? | 11:39 |
| pkern | amitk: A proven allocator is buggy? Fun. | 11:43 |
| pkern | Seriously. fglrx is suggested on laptops but breaks on suspend. "We depend on ATI." is IMHO not that valid as it's a regression over Feisty. | 11:44 |
| pkern | People start to build their own kernels because of this which is at least annoying. | 11:44 |
| lamont | pkern: I have a laptop where I've blacklisted fglrx so that I can have suspend | 11:47 |
| amitk | pkern: http://lwn.net/Articles/229984/ | 11:47 |
| pkern | amitk: I read LWN, kthx | 11:47 |
| pkern | lamont: Possible solution as I currently don't need working 3D acceleration. But then there are users which depend on it (for whatever reason). | 11:48 |
| pkern | amitk: I don't say "let's switch back" but "provide a new flavour and document it properly". | 11:49 |
| lamont | ah, then in that case, you get to choose whether you want 3D or suspend | 11:49 |
| pkern | Maybe I should add a "anymore" here. | 11:49 |
| lamont | until such time as we get a working fglrx driver binary blob. go closed source! | 11:49 |
| lamont | what would the flavor do differently? | 11:50 |
| pkern | There will be free drivers. Maybe for Hardy. | 11:50 |
| kylem | provide a new flavour? | 11:50 |
| pkern | lamont: Use SLAB instead of SLUB. | 11:50 |
| kylem | you mean provide 4 new flavours. | 11:50 |
| lamont | ah, that. | 11:50 |
| pkern | lamont: The driver works fine with 2.6.22, but with SLAB instead of SLUB. | 11:50 |
| lamont | I see. | 11:51 |
| amitk | pkern: considering that kernel freeze is tomorrow, this discussion is moot | 11:51 |
| pkern | amitk: It's not that I haven't spoke up earlier. | 11:51 |
| pkern | lamont: fglrx is even suggested by a nice shiny popup for `more performance' or whatever it states. | 11:52 |
| lamont | mk | 11:52 |
| pkern | lamont: That's one of the key critisism I have here. But if X works properly with fglrx kernel module blacklisted... | 11:52 |
| pkern | Point is that at least my card is not supported by the free drivers. | 11:53 |
| pkern | (For Gutsy that is.) | 11:53 |
| lamont | pkern: works for me... | 11:53 |
| pkern | lamont: Ok. | 11:53 |
| kylem | so what's the problem? does it panic? | 11:53 |
| lamont | of course, I also turn of compiz because I have better things for it to do. | 11:53 |
| pkern | kylem: Suspend hangs with a blinking cursor. | 11:53 |
| lamont | kylem: fails to suspend | 11:54 |
| pkern | lamont: Compiz does not work for fglrx out of the box. | 11:54 |
| lamont | and then you reboot | 11:54 |
| lamont | pkern: I'm fine with that. :-) | 11:54 |
| kylem | if that's the best you can do for debugging information, then i'm afraid i'm just going to point and laugh. | 11:54 |
| pkern | lamont: Me too. | 11:54 |
| pkern | Bah. Please. | 11:54 |
| lamont | kylem: when I was troubleshooting why suspend didn't work with mjg59, we got to the point where he learned that fglrx was loaded and he said "don't do that. kthxbye" | 11:55 |
| lamont | so that was where I stopped | 11:55 |
| pkern | Kernel devs also responded that SLUB is correct and they won't support it. | 11:55 |
| pkern | It's ATI's fault and we know that, but this is not the point here. | 11:55 |
| kylem | the only issue i know of with slub, is that it warns if you double free a pointer. | 11:55 |
| lamont | kylem: and that ati calls it wrong, apparenlty. | 11:56 |
| lamont | for some value of "wrong" | 11:56 |
| kylem | well, comment out that check, and if it works, and you can tell me in the next 30 minutes, maybe i'll consider it. | 11:56 |
| === lamont is frying other fish, lets pkern go for it if he wants | ||
| kylem | sorry, it warns on 0-sized allocations, not double free. | 11:58 |
| pkern | When it only warns that should not pose a problem? | 11:59 |
| kylem | you'd think. | 12:00 |
| pkern | I think the problem are some weird semantics ATI relies on, but I am currently looking for the part to comment out. | 12:01 |
| kylem | well, if they do broken things like that with the allocator, then it's clearly a derived work. | 12:01 |
| kylem | ;-) | 12:01 |
| pkern | The point is that I don't know how to debug it. The display goes black. | 12:03 |
| pkern | i.e. even debug output would not help | 12:03 |
| pkern | And I don't see a printk for a zero-length alloc. | 12:03 |
| pkern | Hm, object_err... | 12:03 |
| kylem | maybe they removed it. | 12:04 |
| pkern | There are things like Alignment padding checks and something about "red zones". | 12:05 |
| pkern | It's just a pity when you know that with SLAB it works fine. | 12:06 |
| mjg59 | Sounds like SLUB works fine | 12:07 |
| mjg59 | It's the thing we don't have the source to that isn't | 12:07 |
| kylem | well, i'm not the only ubuntu kernel person, but it sure won't be me who reverts to slab. | 12:07 |
| pkern | mjg59: If you tell me that there is a free driver for X1400 in Gutsy I will gladly move to that one instead. | 12:08 |
| mjg59 | I thought we'd established you don't need to use the kernel module? | 12:09 |
| pkern | mjg59: Still doesn't solve the source problem, but ok. ;) | 12:09 |
| mjg59 | It means that you don't have kernel problems caused by the thing we can't debug, so... | 12:10 |
| pkern | Ok, it worked now but it showed a "your computer failed to suspend" bubble afterwards. | 12:14 |
| pkern | But nevermind that \: | 12:14 |
| === lamont sometimes gets those bubbles too | ||
| elmo | btw, is there any 'how to debug suspend' failures (where by 'debug' I mean provide enough info for someone else to debug) page somewhere? | 12:17 |
| elmo | my laptop only suspends on AC, breaks on battery | 12:18 |
| mjg59 | Basically, no | 12:19 |
| elmo | mjg59: ok, so when are you next visiting millbank? :-P | 12:19 |
| mjg59 | Not in the near future | 12:19 |
| mjg59 | You going to be in Boston? | 12:19 |
| elmo | yeah | 12:19 |
