| lehjr | I'm trying to fill out a bug report for a null pointer issue in Ubuntu 12.10/kernel 3.5 but when I try to do ""sudo lspci -vvnn > sudo_lspci-vvnn.log" the terminal just hangs and hangs with just "sudo". Any ideas? | 17:35 |
| penguin42 | hmm shouldn't hang, it might ask you for your password at that point - but you shouldn't see a hang | 17:36 |
| lehjr | it doesn't even get to the point of a password | 17:36 |
| penguin42 | does sudo -s get you a shell? | 17:36 |
| lehjr | even just sudo by itself hangs instead of giving the help output of how to use it | 17:37 |
| penguin42 | oh, that's a bit broken | 17:37 |
| penguin42 | lehjr: Is this after the oops happened? | 17:38 |
| lehjr | yes, the oops happens during boot | 17:39 |
| penguin42 | ah hmm | 17:39 |
| penguin42 | lehjr: Well, if it hangs, it hangs - so just put as much info as you can, and do the lspci as non-root and put in the comment saying the sudo hangs | 17:40 |
| lehjr | null pointer at 0000000000000080, there's a similar bug report, but my hardware is different | 17:41 |
| penguin42 | lehjr: Have you got the bug number? | 17:41 |
| lehjr | searching... | 17:42 |
| lehjr | Bug #981877 | 17:44 |
| ubottu | Launchpad bug 979402 in linux (Ubuntu) "duplicate for #981877 Kernel Oops - BUG: unable to handle kernel NULL pointer dereference at 0000000000000080; RIP: 0010:[<ffffffff8165af70>] [<ffffffff8165af70>] mutex_lock+0x20/0x50" [Medium,Triaged] https://launchpad.net/bugs/979402 | 17:44 |
| penguin42 | lehjr: Don't dupe kernel bugs - let the kernel guys do it; although if your oops looks nearly identical it might be worth just adding a comment | 17:45 |
| lehjr | that's the one I was looking at, but I don't believe the cause is the same | 17:46 |
| penguin42 | ok | 17:46 |
| lehjr | the RIP line is different | 17:47 |
| lehjr | I just want to clarify whether or not it is different because it likely won't help if it is marked as a duplicate of the bug noted above | 17:49 |
| penguin42 | file it with the full oops text and details and then lets have a look at it | 17:49 |
| lehjr | ok | 17:49 |
| penguin42 | I mean that one looks related to digital-video tv cards | 17:50 |
| lehjr | about that kernel opps bug report... would the output of "sudo lspci -vvnn" from a different kernel work? I have a working installation with a 3.2 kernel | 18:37 |
| penguin42 | yes, from the same machine - put a big obvious note to say that's what you did | 18:38 |
| penguin42 | lehjr: But you've got the dmesg/oops from the failing one? | 18:38 |
| lehjr | yes | 18:39 |
| lehjr | https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1022351 | 18:39 |
| ubottu | Launchpad bug 1022351 in linux (Ubuntu) "BUG: unable to handle kernel NULL pointer dereference at 0000000000000080" [Undecided,Confirmed] | 18:39 |
| penguin42 | lehjr: OK, that's something wireless related | 18:40 |
| lehjr | so if I pull the wireless card it "should" work then? | 18:41 |
| penguin42 | lehjr: I'd say it's the most likely cuplrit - the last hting in the oops is ieee80211_propagate_queue_wake | 18:42 |
| lehjr | Network controller [0280]: Ralink corp. RT2500 Wireless 802.11bg [1814:0201] (rev 01) | 18:44 |
| lehjr | Subsystem: ASUSTeK Computer Inc. WL-130g [1043:130f] | 18:44 |
| lehjr | apparently that was it | 18:48 |
| penguin42 | lehjr: Can you just add a comment to say that it goes away if you unplug/disable that and add some detail on exactly what wifi card it is? | 18:52 |
| lehjr | yes, working on that atm | 18:52 |
| penguin42 | disappears to get food for a min | 18:53 |
| trism | different module but may be related since the bug seems to be in mac80211: http://thread.gmane.org/gmane.linux.kernel.wireless.general/94058 which seems to be fixed in: http://thread.gmane.org/gmane.linux.kernel.wireless.general/94220 | 18:57 |
| trism | not in linus's tree yet though | 18:57 |
| penguin42 | yeh looks a possible | 19:05 |
| penguin42 | given it is in the queue wake stuff | 19:05 |
| MacGuges | Hi, looks like I installed Quantal on my dad's pc by mistake. I'd like to downgrade him but the package system is stuck on a netbase/ifupdown conflict. ubuntuforums.org/showthread.php?p=12086249#post120862499 Can someone help, thanks? | 20:04 |
| FernandoMiguel | MacGuges: no downgrade supported | 20:04 |
| FernandoMiguel | you either restore from backup | 20:04 |
| MacGuges | I've found a downgrade howto & script, but I can't make progress until I correct this error. | 20:04 |
| FernandoMiguel | or install over... probably won't work so well | 20:04 |
| FernandoMiguel | in most cases, clean install is the way to go | 20:05 |
| FernandoMiguel | MacGuges: if you allow me, how did you install a devel version by mistake!? | 20:05 |
| MacGuges | haha, I can't remember. | 20:06 |
| MacGuges | so download & run the prior iso is the way to go? Fair enough, I'm sure you've got enough trouble fixing the bugs for those who're sticking to it. Huh, you wouldn't know the system was so borked to look at it. | 20:09 |
| FernandoMiguel | it runs pretty well | 20:11 |
| FernandoMiguel | *right now* | 20:11 |
| FernandoMiguel | but can, and will, have serious problem all the way | 20:12 |
| MacGuges | yeah, it appears to work fine, most of the time. He hadn't been complaining, but I knew you couldn't update. | 20:13 |
| FernandoMiguel | ahaha | 20:15 |
| MacGuges | I suppose I wasn't paying attention when I installed it last month :-P | 20:15 |
| FernandoMiguel | you are still serveral months away from the release | 20:15 |
| FernandoMiguel | it's far from ideal for novice users | 20:15 |
| astraljava | MacGuges: Yeah, it's best to reinstall. But just so you know, the version of ifupdown you're trying to install is wrong: $ apt-cache policy ifupdown | 20:18 |
| astraljava | ifupdown: | 20:18 |
| astraljava | Installed: 0.7~beta2ubuntu8 | 20:18 |
| astraljava | Could, or could not be the issue. | 20:20 |
| MacGuges | oh, that may be an effect of the downgrade script I'd found on the wiki. But my issue has been that ifupdown tries to clobber /etc/init.d/networking | 20:21 |
| MacGuges | I see we already have a precise iso here. I wonder if I can do a "repair" options, preserving his existing applications & settings, or if I've got to backup & restore them manually? | 20:24 |
| astraljava | Doesn't do it on mine: http://paste.ubuntu.com/1081751/ | 20:24 |
| MacGuges | huh | 20:24 |
| astraljava | Make sure your package database is up-to-date, and try again. But this is the wrong channel for this, and yeah, it's not officially supported. | 20:27 |
| MacGuges | yeah, I guess not. That would be a "downgrade" | 20:28 |
| MacGuges | thanks anyway guys | 20:29 |
| astraljava | No worries. Good luck! | 20:29 |
| ActionParsnip | hey guys, noticed that the modules folder for the only kernel I had was missing, so took the easy way and reinstalled | 21:54 |
| ActionParsnip | seems faster now... | 21:54 |
