[02:01] Im trying to make a kernel bisect, but my compile is failing, and not outputting an error.. can someone tell me where the error is occurring? http://pastebin.com/Ms19YxMm [02:05] whoops i found it ndiswrapper way at the top [04:06] Im trying to bisect a problem with my rt2x00 wireless drivers. In 3.0.0-16-generic oneiric it works, but in 3.1.0-1-generic precise it does not. How do I get a git pull of changes between those kernels? they are on two separate repositories no? git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git and git://kernel.ubuntu.com/ubuntu/ubuntu-oneiric.git [04:06] Im trying to bisect a problem with my rt2x00 wireless drivers. In 3.0.0-16-generic oneiric it works, but in 3.1.0-1-generic precise it does not. How do I get a git pull of changes between those kernels? they are on two separate repositories no? git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git and git://kernel.ubuntu.com/ubuntu/ubuntu-oneiric.git [04:07] you can add the other one as a remote head [04:07] dunno how bisect will work with that, but they're like any other label afaik [04:08] thanks [05:02] i'm running a machine on 12.04 and the last few kernel updates have failed to find my network driver. i'm wondering what I should do wrt to reporting that. [05:03] is it an rt2x00 driver device? [05:04] there are a lot of people that have been talking about network drivers disappearing and stuff, if not the changelog for the kernel; there should be other people asking in bug reports [05:07] k, will keep searching launchpad -- and add what info I can find there. [07:14] I have precise beta2 installed, can I run a 2.6 kernel? [07:19] The first commit in the git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git is for a 2.6.0-r2 kernel, can I compile this and run it on my precise machine? [07:25] I Have to bisect test my r2x00 wireless drivers, they worked in oneiric, but not in precise. I have the git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git cloned, and tried to checkout from the very first commit ( to see if the earliest version in precise works ) but that version gives debian/rules: No such file or directory [07:26] Is there a trick to finding which commit in precise begins, and oneiric ends? [07:26] Precise git doesn't start where oneiric ends does it? [07:26] have you looked at git log from precise for the files related to your driver? [07:26] yes [07:27] when you say it doesn't work; how do you mean [07:28] and I tried compiling at points where those happened, but the problem still persists… It works in oneiric 3.0.0-18-generic [07:29] describe "doesn't work" with the precise kernel [07:29] The wifi driver will work, but if I go to speediest and check the speed, it will get half way through the test, then stall…. I have to restart my network to get it running again [07:29] ok [07:29] sorry speediest ( speediest.net ) [07:30] speedtest.net [07:30] you may find it easier to bisect linux-wireless [07:30] did you ask anyone if they knew about this problem already? [07:30] in oneiric it works fine, precise is broken.. So I checked out precise, I thought precise would start at a version where oneiric ends [07:31] Yes, they hadn't, and I created a bug in ubuntu https://www.google.ca/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&ved=0CD4QFjAD&url=https%3A%2F%2Fbugs.launchpad.net%2Fbugs%2F965043&ei=2rJ2T5y0D8ehgwer3dnTDg&usg=AFQjCNFHRs4kuBd6E1IcL1Enbb14B6r_vw&sig2=BDeONK-wyDkWkskMTANcgg&cad=rja [07:31] sorry [07:32] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/965043 [07:32] Launchpad bug 965043 in linux "rt2x00 random stalls in AP Mode - 12.04 Beta 1" [Medium,Confirmed] [07:32] They asked me to bisect it, Im trying to find a good point in precise ( where the drivers work ) but so far nothing [07:34] I wanted to checkout precise to the very first commit in that repository, but that is a 2.6 kernel.. weird, I thought it would be like 3.0.18, ( like where oneiric ended ) [07:34] well they're both copies of the same repo, with some stuff on top [07:35] So, in precise , should I be able to find 3.0.18 kernel? [07:35] Because I couldnt [07:35] there's no tag for it? [07:35] I greped for Ubuntu ( as in Ubuntu-3.0.18 ) [07:35] no, they only have two tags [07:36] Oh, sorry more than two, but they start at Ubuntu-3.1.0-1.0 ( and I built that one and it didn't work, same problem ) [07:37] How can I find the changes between oneiric ( 3.0.18 ) and precise ( 3.1.0-1.0 ) ? [07:38] get the commit hash for 3.0.18 in oneiric and use it as "good" in the precise tree, i dunno how to find the closest common commit but there are lots of common commits [07:39] wrostek: there are plenty of ubuntu tags in precise [07:39] maybe you didn't pull all the tags down [07:39] git log master -g --grep=Ubuntu- [07:40] that didn't pull them down? [07:40] that doesn't pull down anything [07:40] ( sorry I'm kind of new at this ) [07:40] git tag -a will list all the tags [07:40] or just git tag rather [07:41] oh cool, [07:41] then you can to a git checkout [07:41] and build from there [07:41] ok thanks [07:41] I wouldn't start at the first tag, I'd start at the last known good tag. [07:41] i will try this [07:42] unless you've never run precise before, then you're out of luck I guess. [07:42] I think it is v3.0-rc7 ( i think thats the last oneiric ) [07:42] thanks tdmackey [07:42] yeah, I'm just saying going in order will take a long time. Binary search is a better approach if you have no other knowledge as to a decent version. [07:45] wrostek: also of note, if you look at the top of the tag list youll see the ubuntu-version tags. the non-ubunutu tagged points are the vanilla kernel tags. [07:47] you can still just bisect net/ or net/wireless plus your driver too [07:48] Maybe, I think they were giving me the impression the problem may be somewhere else than the driver though [07:49] did you already see git log 3780d038fdf4b5ef26ead10b0604ab1f46dd9510 ? [07:49] Is that about stalled rt2x00 [07:49] yes, from march 9th [07:49] Yes, that did not fix this problem it was weird, [07:50] I think that guy needs to take another look [07:51] the log entry is pretty concise [07:52] http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2012-March/004651.html [07:53] Yes, I mentioned that in my bug report, ( and that fix is already in the precise rt2x00 drivers in beta1 ) but it did not help https://bugs.launchpad.net/ubuntu/+source/linux/+bug/965043 [07:53] Launchpad bug 965043 in linux "rt2x00 random stalls in AP Mode - 12.04 Beta 1" [Medium,Confirmed] [07:54] i didn't suggest it solved your problem, but that you may contact him [07:54] or respond to the thread [07:54] One question, is Ubuntu-3.0.0-1208.19 later than Ubuntu-3.0.0-13.21 [07:55] Yes, I was thinking about it, but I don't know how much spam he gets already from people with driver issues [07:56] -13 is later [07:57] thansk [07:57] thanks [13:17] hi [13:17] I have installed precise-beta1 and updated to recent kernel [13:18] this is linux-image-3.2.0-21-generic (3.2.0-21.34) [13:18] (also I did all other software updates) [13:19] I installed via wubi on an existing win7 partition on samsung series-5 ultrabook [13:19] on shutdown the machine freezes [13:19] I have to power-off via power-button [13:20] (I had no look into syslogs, yet) [13:20] with 3.2.0-17.27 and 3.2.0-20.33 kernels I am not aware I had this new issue [13:22] any known issue?
