[10:38] <eren> I've compiled ubuntu-vivid kernel, I successfully booted it and I now have debug symbols at /usr/lib/debug/. when i try to use iperf with -k /usr/lib/debug/boot/vmlinx... option, it reports vmlinux cannot be used
[10:38] <eren> sorry, iperf = perf
[10:39] <eren> I compiled perf in tools/perf/ directory, btw
[10:44] <eren> oh sorry, it was compiled without drawf support, my bad
[10:44] <eren> just installed required dwarf libs and it's now ok :)
[14:25] <ChrisP1948> Since kernel version after 3.13.0-35 my system has been hanging after about 1 1/2 days with kernel: [106482.820016] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring idle at first I thought it was totally locked up but on further inspection I noticed that all background processes continued to run. I've filed two bugs, one on Launchpad and added to another at freedesktop.org, https://bugs.launchpad.net/
[14:25] <ChrisP1948> ubuntu/+source/linux/+bug/1402331 and https://bugs.freedesktop.org/show_bug.cgi?id=75394. 
[14:26] <ChrisP1948> For the Ubuntu report I've been asked to do a 'kernel bisection' I've got the directions but really not sure still after reading how to go about it.
[16:51] <tseliot> apw: the nvidia packages that I'm going to upload soon seem to be working fine with 346. I need to figure out a few more (unrelated) details before I upload though
[16:51] <apw> tseliot, rocking 
[16:51] <tseliot> :)
[17:41] <hallyn> sforshee: hey, just checking, has there been any discussion anywhere about your ext4-userns patchset?  
[17:43] <sforshee> hallyn: I haven't posted them yet, I'm currently in the process of auditing vfs and lsm code to find everything which needs to be change there.
[17:43] <sforshee> I hope to have something fairly well tested later this week
[17:48] <hallyn> sforshee: cool.  i'll play as soon as you say they're ready :)
[17:48] <sforshee> hallyn: I'll welcome the testing :-)
[17:48] <sforshee> just lots of nooks and crannies to go through
[17:49] <hallyn> sforshee: maybe i'm too tired for this, but how do you use them right now?  you pass loopback into the userns?
[17:51] <sforshee> hallyn: yep, I make a loopback device and bind mount it into a container
[17:51] <hallyn> ok, so if this goes anywhere i guess it may become rationale for a real loop fix
[17:51] <hallyn> thanks sforshee - ttyl
[23:40] <ChrisP1948> I need to build kernel version 3.13.0-35 so I can run a kernel bisection to try and debug this issue I and others are having. In the instructions for building a kernel is says "sudo apt-get build-dep linux-image-$(uname -r)" do I put the version I want to build in place of uname-r?
