| mowthegrass | Hi There - Anyone facing issues with 3.19 /4.2 kernel, All DELL servers running on 3.19/4.2 kernel on reboot does not boot and gets stuck with message random: LVM unrandom read with 33 bits of entropy available | 09:37 |
|---|---|---|
| mowthegrass | is it a BUG | 09:37 |
| apw | mowthegrass, i'd say it is likely a bug indeed. that last message doesn't look to be anything other than a warning about early use of entropy before it is really very random; from my reading it is not a blocker | 09:44 |
| apw | mowthegrass, well it _might_ indicate we are triggering transfer of ral randomness into urandom, so it might indicate a block, very hard to be sure | 09:46 |
| apw | mowthegrass, do the machines come out of it after some time? | 09:46 |
| apw | mowthegrass, but either way, you should file a bug "ubuntu-bug linux" and add the details | 09:47 |
| mowthegrass | apw:No they dont come up | 10:22 |
| apw | mowthegrass, do they come up from cold, or do you have to boot an older kernel | 10:23 |
| mowthegrass | it just drops to switched clocksource tsc | 10:23 |

| mowthegrass | apw,Thanks on your input | 12:33 |
| fg_ | afaict, xenial's kernel is not affected by CVE-2016-6187 (the apparmor setprocattr oops) because the causing commit bb646cdb12e75d82258c2f2e7746d5952d3e321a is not contained in the 4.4 stable kernels - is that correct? | 13:14 |
| arges | https://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-6187.html looks like it | 13:36 |
| fg_ | arges: thanks, I only looked at / knew about http://kernel.ubuntu.com/reports/kernel-cves.html (which does not list CVE's that don't affect) | 13:39 |
| fg_ | arges: although your link also says "needs-triage" for some of the entries (e.g., source: linux) ;) | 13:43 |
| arges | tyhicks: ^^^ | 13:45 |
| tyhicks | fg_: hello | 14:40 |
| tyhicks | fg_: that's correct (xenial is not affected) | 14:40 |
| fg_ | tyhicks: thanks! | 14:41 |
| tyhicks | fg_: since I populated the break-fix line with the git hashes of the commit that introduced the flaw and the commit that fixed the flaw, a bot will come through and update the status of all the kernels | 14:41 |
| tyhicks | fg_: I left it as 'needs-triage' intentionally because of that | 14:42 |
| fg_ | tyhicks: okay - that sounds reasonable ;) thanks for clearing it up! | 14:49 |
| tyhicks | no problem :) | 14:53 |
| dmj_s76 | is it still possible to get a patch for a nasty bug in the nouveau driver? | 15:56 |
| dmj_s76 | in time for the kernel cycle on the 16.04.1 iso? | 15:57 |
| apw | dmj_s76, is it in the kernel itself ? the last kernel has been uploaded (in theory) | 15:57 |
| apw | dmj_s76, though depending on severity and recoverablility, you never know | 15:58 |
| dmj_s76 | apw: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/tree/drivers/gpu/drm/nouveau/nouveau_drm.c | 15:58 |
| apw | dmj_s76, what is the bug number | 15:58 |
| dmj_s76 | apw: It prevents installation and booting until you install the nvidia proprietary drivers with Pascal (There is a workaround, but it involves the user knowing about modelines and vga modes) | 15:59 |
| dmj_s76 | apw, looking that up now | 16:00 |

| dmj_s76 | apw: couldn't find a bug report so filed one: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602340 | 16:30 |
| ubot5 | Launchpad bug 1602340 in linux (Ubuntu) "nouveau: boot hangs at blank screen with unsupported graphics cards" [Undecided,Incomplete] | 16:30 |
| apw | dmj_s76, and is there a fix yet ? | 16:30 |
| apw | dmj_s76, i assume the code thinks it supports those cards | 16:31 |
| dmj_s76 | apw: I believe so. Ben Skeggs worked on one yesterday, which I'm planning to test today. | 16:31 |
| apw | dmj_s76, could you add any information you have on the fix to the bug as well pls | 16:31 |
| dmj_s76 | apw: https://github.com/skeggsb/nouveau/commit/11fcd1624b0a1c73fe3b2fa15c3cc45816da0470 | 16:32 |
| dmj_s76 | apw: added | 16:35 |
| apw | dmj_s76, thanks ... | 16:38 |
| apw | dmj_s76, and ... keep that bug updated with your testing too pls | 16:39 |
| dmj_s76 | Will do, really hoping to get this in the iso, since it's an issue that will make most users consider Ubuntu uninstallable if they have a recent GPU. | 16:42 |

| apw | dmj_s76, i assume you have a range of affected and non-affected GPUs you could test this on to make sure it does not regress older kit | 17:00 |
| apw | dmj_s76, would a test kernel help your testing ? | 17:02 |
| dmj_s76 | apw: Yes, we have 9 series and 7 series to test for regression | 17:13 |
| apw | dmj_s76, cool, could you document that in the bug as well | 17:13 |
| kamal | dmj_s76, I've built a Xenial test kernel with the nouveau patch applied: http://people.canonical.com/~kamal/lp1602340/ ... does that advance your testing efforts? | 17:42 |
| dmj_s76 | apw: Thanks for the build. I've tested the patched kernel on our hardware and it allows clean installs to boot into unity without trouble. | 20:16 |
| dmj_s76 | No regressions on the older nvidia hardware we have. | 20:16 |
| apw | kamal, ^ | 21:51 |
| dmj_s76 | kamal: thanks for the build...fixes boot issues with current gen nvidia gpus nicely | 22:08 |
| dmj_s76 | If we can get that into the iso, it'll save quite a bit of systems from being effectively uninstallable. | 22:09 |
| kamal | dmj_s76, yes, saw your feedback, thanks -- we are indeed going to get it into the Xenial ISO for ya | 22:11 |
| dmj_s76 | kamal: Thanks...that'll really help make the Ubuntu install experience better. | 22:22 |
| kamal | dmj_s76, we agree! thanks very much for your work on this. | 22:24 |
