| JPelletier | Hi, someone can help me investigate a boot hang issue? | 14:11 |
|---|---|---|
| JPelletier | Trying to get more logs, don't know if it's possible / how | 14:11 |
| apw | JPelletier, boot logs from what kind of setup, and how is it hanging | 14:54 |
| apw | JPelletier, you might find you have more logs than you think if you sysrq and request a sync | 14:54 |
| apw | JPelletier, and booting without splash and with debug sometimes gets you more information | 14:55 |
| JPelletier | apw: I tried to boot with earlyprintk=efi and my system freeze right after [ 0.00000] bootconsole [earlyefi0] disabled | 15:03 |
| JPelletier | apw: System freeze randomly on reboot, like once every 20-30 reboot when I'm using 2GB memory and once every 100 reboots or more when using 4GB memory | 15:04 |
| apw | well that is where the bootconsole hands off to the kernle console and there is a period where no messages come out, they are buffered | 15:04 |
| apw | frankly that is going to be a pig to figure out, if it happens so early you get no diagnostics | 15:05 |
| apw | and is that uncommon | 15:05 |
| JPelletier | Ok and is there a way to know why it's freezed? I have nothing in journalctl when the freeze occur | 15:05 |
| JPelletier | Since changing my memory have an impact, any idea on what could be the cause? Ran memtest on both without issue | 15:06 |
| apw | JPelletier, pretty much not from what you have, if you know of a kernle which does not have this issue for instance it might be findable via a bisect | 15:06 |
| apw | or you might get somewhere adding debugging _if_ you can get some output out, but that is tricky if it is happening that early | 15:07 |
| apw | or if you have one of those debug boards which give you hints as to status | 15:07 |
| JPelletier | I tried with server 16.04.2 16.10 and 17.04, also tried Kernel 4.12.2 in 17.04 - Same issue | 15:07 |
| JPelletier | No debug boards, don't know what this is? | 15:08 |
| apw | int 80 board have digits on the you can set in boot, not that then | 15:09 |
| JPelletier | I can recompile the kernel, it's easy, if it can help | 15:09 |
| JPelletier | I tried to boot with earlyprintk=efi,keep but it really slow, like every line take 3-4 seconds to print | 15:10 |
| JPelletier | BTW, it's on an Intel NUC6CAY | 15:11 |
| apw | does that nuc have the remote serial interface thing built in? | 15:16 |
| apw | you might have more luck sending the console there if so | 15:16 |
| JPelletier | Humm not sure what you talking about, is this Serial-over-LAN ? | 15:18 |
| apw | yes that | 15:18 |
| JPelletier | I'm trying to find, not sure since it's an entry model | 15:20 |
| JPelletier | No it's not supported, it's a feature of vPro and I don't have vPro | 15:24 |
| banshi | hello all | 20:22 |
| banshi | take a look please: http://paste.ubuntu.com/25134780/ How do I compile linux-headers* after that error? | 20:22 |
| apw | that looks like a debian kernel package form perhaps ? | 20:28 |
| banshi | man, I'm real dummy in kernel/deb building | 20:33 |
| banshi | just tried to do like https://www.cyberciti.biz/faq/debian-ubuntu-building-installing-a-custom-linux-kernel/ | 20:34 |
| banshi | apw, I'm building it on debian, yes | 20:35 |
