mthaddonhowdy folks, I'm seeing some issues on a Thinkpad X220 (64 bit) with oneiric - occasional hangs and seeing "general protection fault" in dmesg as well as what looks like stack traces. I *think* I have a sandybridge processor, but not sure how I confirm, and what my options are if that's the case09:49

ckingapw, for bug 851141 you enabled the MTRR sanitizer by default - have we seen any negative issues from enabling this?  If not, should we consider enabling it for earlier releases as a SRU at some point?10:46

apwcking, no your bug is private11:26
apw2. install all updates (sudo apt-get update && sudo apt-get upgrade)11:32
apwcking, this here really should be a dist-upgrade else you don't get the new packages you need installed11:33

apwtgardner, you pulled wireless-crda into ubuntu didn't you ?  there seems to be two packages for it now, see discussion on #ubuntu-devel13:37
tgardnerapwsynced from upstream ?13:38
tgardnerapw ^13:38
tgardneror debian13:38
apwtgardner, i'd guess debian, package is call crda and we have wireless-crda as well13:38
tgardnerapw, lemme check it out. maybe we can drop wireless-crda13:39
apwtgardner, version numbers wise we seem to have a much never version -- maybe13:41
tgardnerapw, it hasn't been updated since April13:41
apwtgardner, ours of theirs13:42
tgardnerapw, theirs13:42
apwi'd guess teh DB needs updating more often than that13:42
apwthough of course it just may not have been sync'd13:42
apwtgardner, seems that version is the latest in debian, so they are not very active with it13:45
apwtgardner, we didn't need it until lucid or later right ?  so perhaps they arn't really using it yet13:45
tgardnerapw, I'm wondering why we synced it without an explicit request.13:46
apwtgardner, ahh it seems the regdb is in a separate package, which is in sync13:46
tgardnerapw, yes13:46
apwso the combination may be as good as what we have13:46
apwtgardner, yeah i suspect we autosync all of universe without intervention13:46
tgardnerapw, the issue when I packaged it for Lucid was that many of the build tools were not in main13:47
apwthe suggestion is that our package only varies slightly from the combination of those two.  something to consider merging i suspect13:47
tgardnerapw, functionally there should be no difference.13:49
apwso perhaps we literally just want to flip the dependancy over13:50
* apw leaves it with tgardner :)13:50
realubotI want to install kernel 2.6.39 in Ubuntu 11.04 but the kernel doesn't seem to be in the kernel PPA?13:54
realubotHow do I install the kernel without having to install it from a deb file?13:54
realubotKernel 2.6.39 is "missing" in this PPA: https://launchpad.net/~kernel-ppa/+archive/ppa13:55
realubotWhy?13:55
apwthat PPA never was the vehicle for those kinds of builds ?13:55
apwthat PPA is a staging ground for test builds and experiemental packages13:55
realubotOk.13:56
apwwhy do you want 2.6.39 in the first place?  thats an odd version to want13:56
realubotapw: Well. There is a bug in the 2.6.38 version så I thought it would be a great idea to upgrade just one step where I have red the bug shall be solved.13:57
realubot*so13:57
tgardnerapw, bug #856421 deferred until P series13:58

realubot"Thanks for confirming that kernel 2.6.39 fixes the issue."13:59
tgardnerrealubot, use compat-wireless from linux-backports-modules13:59
apwwhat he said13:59
apwrealubot, you are on natty right ... so to get the 2.6.39 wireless you'd want linux-backports-modules-cw-2.6.39-natty-generic14:09
* ogasawara back in 2014:11
realubotapw: So the bug I linked will be solved using the linux-backports-modules-cw-2.6.39-natty-generic14:15
apwrealubot, it is highly likely that if a .39 kernel would solve your issue, and it is a wireless issue, then the backports there are likely to carry the same fix.  testing those before moving to unsupported packages is a good idea14:20
realubotapw: Ok, thank you for all help. I'll try it out and see if that solves my wifi problem. Thanks!14:23
