[12:07] <shay_shay> hello, i'm getting deadlocks when writing large amounts of data to my HDD
[12:07] <shay_shay> cpu load never is higher than 30%
[12:12] <shay_shay> i cant seem to find a bug report for it. is there a way to filter the bug reports by version?
[12:26] <BluesKaj> 'Morning
[12:28] <shay_shay> morning
[13:46] <smoser> anyone else have a recent upgrade causing compiz to eat cpu?
[13:46] <smoser> its basically sitting at 50-60% cpu usage, and X at 10-20%
[13:48] <danielhyuuga> hi is there anyway to submit feedback of ubuntu 14.10?
[13:49] <smoser> danielhyuuga, generally i think bugs are the most common way.
[13:50] <danielhyuuga> nah not reporting bugs, just some feedback
[13:51] <danielhyuuga> oooh u mean use the bug report thing?
[13:54] <Pici> What sort of feedback?
[13:55] <danielhyuuga> the appearance
[14:01] <danielhyuuga> liked the new appearance but it would be nice if the menu bar app window stays the same like how v13 & v14 appear, that ¨compact¨ menu bar thing
[14:01] <danielhyuuga> looks great on bigger screen but netbooks screens disagreed with it
[14:58] <smoser> fwiw, just opened https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1355196
[22:41] <shay_shay> hello. i noticed on kernel 3.16 i am having deadlocks when trying to copy large files. I switched to 3.15.9 and the problem went away. I couldn't find the bug on the bug tracker, but maybe i'm not searching for the right keywords?
[22:42] <jtaylor> which filesystem are you using?
[22:45] <shay_shay> btrfs. at first I thought it was due to my file system but they helped me in #btrfs determine it was not, and then by asking around I found someone who had the same problem with ext4 (a trusted source, not just a random person)
[22:47] <shay_shay> it seems to be file system independent so far
[22:48] <shay_shay> the test is, copy  a linux iso from one directory to another, and the cpu load will never go above 30%, but on 3.16 my mouse and keyboard will lock up for a few seconds at a time until the transfer is done
[22:49] <shay_shay> on 3.15 its normal, i can continue to multi task
[22:50] <jtaylor> hm I guess you could bisect the kernel to find the change that caused it
[22:52] <shay_shay> this looks simple enough https://wiki.ubuntu.com/Kernel/KernelBisection
[22:52] <shay_shay> i can do that
[22:54] <shay_shay> i am assuming someone else has reported it as it took me less than ten minutes to find another who had the same problem... however i cant figure out how to search the bugs
[22:54] <shay_shay> i dont see an "advanced" search anywhere
[22:56] <jtaylor> you mean on launchpad?
[22:56] <rww> https://launchpad.net/ubuntu/+source/linux/+bugs?advanced=1
[22:56] <jtaylor> advanced search is below the search bar
[22:56] <jtaylor> but maybe the bug has not been reported there yet
[22:56] <jtaylor> I'd first try a mainline kernel if the issue is present there too, I think there are prebuilt binaries for them somewhere
[22:57] <rww> http://kernel.ubuntu.com/~kernel-ppa/mainline/
[22:57] <rww> (it's not actually a PPA, the URL lies)
[22:57] <jtaylor> yes that
[22:58] <jtaylor> bisecting manually via the rcs should also help narrowing down the commits you have to bisect in the source
[23:00] <shay_shay> yeah i tried upgrading the kernel, although i didnt try ALL of the 3.16 kernels
[23:00] <shay_shay> so i should narrow it down to the first kernel with the problem and the bisect it
[23:00] <shay_shay> then*
[23:02] <jtaylor> well you can try 3.16rc1 and if it has the issue you will have to bisect from 3.15 to 3.16rc1. else from rc1 to what is in utopic now
[23:02] <jtaylor> or just start on the source directly, I guess it depends on how fast your machine builds the kernel
[23:04] <shay_shay> installing rc1 now
[23:05] <TaZeR> hey guys im having an issue with buntu 14.10 and creating a persistance liveusb
[23:05] <TaZeR> the usual methods before arnt working
[23:05] <TaZeR> would someone be kind enough to enlighten me?
[23:42] <Beldar> TaZeR, The usb loaders have a option to do this, what is the issue in detail, I have about  min to help you.
[23:42] <Beldar> 5 min*
[23:57] <shay_shay> 3.16rc1 wouldnt even boot
[23:58] <shay_shay> i'll take a crack at the git bisect thing in a few days
