| hyperair | hi. has anyone seen the 3.18 kernel hang bug? | 07:16 |
|---|---|---|
| hyperair | the one that wedges everything and disables everything except alt+sysrq+b | 07:16 |
| * hyperair thinks it's the same as the hpet bug | 07:16 | |
| === gerald is now known as Guest11798 | ||
| apw | hyperair, not seen any particular mention of that no | 09:08 |
| hyperair | damn | 09:08 |
| hyperair | it keeps hitting me, and for some reason nobody else sees it | 09:08 |
| * hyperair sighs | 09:08 | |
| apw | hyperair, does it happen with the v3.19 in the CKT PPA? as that will be our kernel shortly anyhow | 09:08 |
| hyperair | apw: dunno, i just compiled my 3.19 kernel. haven't rebooted yet | 09:09 |
| cristian_c | hello | 09:09 |
| cristian_c | apw, Have you read the paste? | 09:09 |
| apw | cristian_c, i have no indication in my backscroll that you told me where it was after you said you'd do it; but i have been travelling | 09:36 |
| cristian_c | apw, http://pastebin.com/TVmxXzUZ | 09:37 |
| apw | cristian_c, that looks comprehensive to me | 09:39 |
| cristian_c | ok | 09:39 |
| cristian_c | apw, ok, also, I've to open an upstream report for a regression | 10:00 |
| cristian_c | related to this bug | 10:00 |
| cristian_c | in total, two reports | 10:01 |
| cristian_c | I must collect info in kernel format for an upstream bug report | 11:01 |
| cristian_c | the upstream bug report should be about a regression | 11:02 |
| cristian_c | How can I locate the specific commit, exactly? | 11:02 |
| cristian_c | Any ideas? | 11:02 |
| apw | cristian_c, the specific commit which introduced the regression ? | 11:18 |
| cristian_c | apw, yes | 11:20 |
| cristian_c | correct | 11:20 |
| cristian_c | I think they request the exact kernel version | 11:20 |
| apw | the exact kernel version is easier, you would use the mainline builds to narrow in on it, in a bisection style | 11:23 |
| cristian_c | apw, ok, so have I to try many kernel until I find the nearest previous version and the nearest next version? | 11:24 |
| cristian_c | to the kernel version has introduced the regression | 11:25 |
| apw | cristian_c, right exactly that, but you do it in divide-and-conquor manner, so | 11:26 |
| cristian_c | ok | 11:26 |
| apw | say you know it worked in 3.2 and not 3.16 you'd pick like 3.9 first and then you have gotten rid of half either result | 11:26 |
| apw | cristian_c, i would use the prebuilt test kernels in the ubuntu mainline archive, so you don't have to make any | 11:27 |
| cristian_c | 3.8.0 is not affected by the regresssion | 11:27 |
| cristian_c | apw, can I use the prebuilt kernels even if I've to report in the upstrem? | 11:28 |
| cristian_c | *to the | 11:28 |
| cristian_c | to locate the regression version | 11:28 |
| cristian_c | apw, usually I download the kernel version from mainline kernel archive | 11:29 |
| cristian_c | http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D | 11:29 |
| cristian_c | and I always install three packages: headers, headers-generic, linux-image | 11:30 |
| apw | cristian_c, yes, those kernels are mainline code exactly, there is no ubuntu patches on those | 11:50 |
| cristian_c | ok, usually I install the mainline .deb packages | 11:52 |
| cristian_c | for the prebuilt is the same , I think | 11:52 |
| cristian_c | *prebuilt kernels | 11:52 |
| apw | i believe we are talking about the same ones yes, those are suitible for a bisect, and for reporting exact versions to upstream | 11:52 |
| apw | as they are unmodified upstream code, built on ubuntu for debugging | 11:52 |
| cristian_c | apw, anyway, I've to identifying the mantainer | 12:08 |
| cristian_c | If the bug is not in USB, the first step in reporting a bug upstream is to find the maintainer of the driver for the bug from the MAINTAINERS list. Here are some typical scenarios and suggested mailing list and procedures: | 12:09 |
| cristian_c | in the first case | 12:09 |
| cristian_c | If this is a regression, CC the submitter of the regression commit. | 12:09 |
| cristian_c | in the second case | 12:09 |
| cristian_c | http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/MAINTAINERS | 12:10 |
| apw | if you can find the before and after mainline commit, we can ask joe to do a proper bisect for you to get the actual commit for it | 12:10 |
| cristian_c | I'll try | 12:12 |

| sarnex | hi guys, i noticed the automatic DEB build of the 3.19 kernel on kernel.ubuntu.org failed, is this a known issue? | 14:44 |
| apw | sarnex, failed how so ? | 14:47 |
| sarnex | apw: BUILD.LOG.amd64 and BUILD.LOG.i386 say "Access not authroized" and there are no debs in the filder | 14:47 |
| sarnex | apw: see here http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/ | 14:48 |
| apw | sarnex, thanks, sorting | 14:54 |
| sarnex | apw: awesome thanks | 14:54 |
