| 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 | 10:38 |
| eren | I compiled perf in tools/perf/ directory, btw | 10:39 |
| eren | oh sorry, it was compiled without drawf support, my bad | 10:44 |
| eren | just installed required dwarf libs and it's now ok :) | 10:44 |

| 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 | 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. | 14:26 |

| 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 |

| hallyn | sforshee: hey, just checking, has there been any discussion anywhere about your ext4-userns patchset? | 17:41 |
| 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 | 17:43 |
| 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 | 17:48 |
| hallyn | sforshee: maybe i'm too tired for this, but how do you use them right now? you pass loopback into the userns? | 17:49 |
| 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 | 17:51 |

| 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? | 23:40 |
