osmosiscool 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
zulrtg__: im talking to him about it already ;)06:12
osmosisrtg__: yah, but he says  "that grub error has to do with the meta package which something i dont have control over"06:13
zulactually its probably update-grub that is erroring out06:14
osmosiszul: true, but even when I manually put the kernel into grub... thats when I get the error 13 on boot...invalid executable.06:14
osmosiszul: update-grub just doesnt put it in the menu.lst, probably can tell its not valid.06:14

ScottKBenC: Not that I know of.  I'm a user as far as the kernel goes.07:59
BenCScottK: then we can't put a fix in yet :)07:59
ScottKBenC: Of course.  But if we're past the point where a fix could go in, then I'll stop trolling for a kernel hacker to help me figure it out.08:00
BenCScottK: it's possible, but all depends on timing and severity08:00
ScottKBenC: Thanks.08:00
ScottKI suspect that the problem centers around /proc/acpi/thermal_zone/THRM/cooling_mode changing from "cooling mode:active" to "0 - Active; 1 - Passive" from Feisty to Gutsy, but I have no idea where to look for how that got changed or where to change it back.  Hints from anyone would be appreciated.08:06

pkernIs there something speaking against a SLAB kernel flavour apart from the fact that it may be too late?11:32
amitkpkern: buggy?11:39
pkernamitk: A proven allocator is buggy? Fun.11:43
pkernSeriously. 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
pkernPeople start to build their own kernels because of this which is at least annoying.11:44
lamontpkern: I have a laptop where I've blacklisted fglrx so that I can have suspend11:47
amitkpkern: http://lwn.net/Articles/229984/11:47
pkernamitk: I read LWN, kthx11:47
pkernlamont: 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
pkernamitk: I don't say "let's switch back" but "provide a new flavour and document it properly".11:49
lamontah, then in that case, you get to choose whether you want 3D or suspend11:49
pkernMaybe I should add a "anymore" here.11:49
lamontuntil such time as we get a working fglrx driver binary blob.  go closed source!11:49
lamontwhat would the flavor do differently?11:50
pkernThere will be free drivers. Maybe for Hardy.11:50
kylemprovide a new flavour?11:50
pkernlamont: Use SLAB instead of SLUB.11:50
kylemyou mean provide 4 new flavours.11:50
lamontah, that.11:50
pkernlamont: The driver works fine with 2.6.22, but with SLAB instead of SLUB.11:50
lamontI see.11:51
amitkpkern: considering that kernel freeze is tomorrow, this discussion is moot11:51
pkernamitk: It's not that I haven't spoke up earlier.11:51
pkernlamont: fglrx is even suggested by a nice shiny popup for `more performance' or whatever it states.11:52
pkernlamont: That's one of the key critisism I have here. But if X works properly with fglrx kernel module blacklisted...11:52
pkernPoint is that at least my card is not supported by the free drivers.11:53
pkern(For Gutsy that is.)11:53
lamontpkern: works for me...11:53
pkernlamont: Ok.11:53
kylemso what's the problem? does it panic?11:53
lamontof course, I also turn of compiz because I have better things for it to do.11:53
pkernkylem: Suspend hangs with a blinking cursor.11:53
lamontkylem: fails to suspend11:54
pkernlamont: Compiz does not work for fglrx out of the box.11:54
lamontand then you reboot11:54
lamontpkern: I'm fine with that. :-)11:54
kylemif that's the best you can do for debugging information, then i'm afraid i'm just going to point and laugh.11:54
pkernlamont: Me too.11:54
pkernBah. Please.11:54
lamontkylem: 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
lamontso that was where I stopped11:55
pkernKernel devs also responded that SLUB is correct and they won't support it.11:55
pkernIt's ATI's fault and we know that, but this is not the point here.11:55
kylemthe only issue i know of with slub, is that it warns if you double free a pointer.11:55
lamontkylem: and that ati calls it wrong, apparenlty.11:56
lamontfor some value of "wrong"11:56
kylemwell, 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
kylemsorry, it warns on 0-sized allocations, not double free.11:58
pkernWhen it only warns that should not pose a problem?11:59
kylemyou'd think.12:00
pkernI think the problem are some weird semantics ATI relies on, but I am currently looking for the part to comment out.12:01
kylemwell, if they do broken things like that with the allocator, then it's clearly a derived work.12:01
pkernThe point is that I don't know how to debug it. The display goes black.12:03
pkerni.e. even debug output would not help12:03
pkernAnd I don't see a printk for a zero-length alloc.12:03
pkernHm, object_err...12:03
kylemmaybe they removed it.12:04
pkernThere are things like Alignment padding checks and something about "red zones".12:05
pkernIt's just a pity when you know that with SLAB it works fine.12:06
mjg59Sounds like SLUB works fine12:07
mjg59It's the thing we don't have the source to that isn't12:07
kylemwell, i'm not the only ubuntu kernel person, but it sure won't be me who reverts to slab.12:07
pkernmjg59: If you tell me that there is a free driver for X1400 in Gutsy I will gladly move to that one instead.12:08
mjg59I thought we'd established you don't need to use the kernel module?12:09
pkernmjg59: Still doesn't solve the source problem, but ok. ;)12:09
mjg59It means that you don't have kernel problems caused by the thing we can't debug, so...12:10
pkernOk, it worked now but it showed a "your computer failed to suspend" bubble afterwards.12:14
pkernBut nevermind that \:12:14
=== lamont sometimes gets those bubbles too
elmobtw, 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
elmomy laptop only suspends on AC, breaks on battery12:18
mjg59Basically, no12:19
elmomjg59: ok, so when are you next visiting millbank? :-P12:19
mjg59Not in the near future12:19
mjg59You going to be in Boston?12:19
mjg59Yeah, so only three and a half weeks away12:20
mjg59That's kind of weird, though12:20
mjg59I can't think of any obvious reasons for that12:20
