| mamarley | It looks like the AMD64 build of the 4.5.4 mainline kernel failed: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5.4-yakkety/BUILD.LOG.amd64 | 00:30 |
|---|---|---|
| kees | we need a new x86_64 flavor that disables CONFIG_COMPAT. :) | 02:29 |
| mamarley | Another thing I have noticed is that the 4.6-rc mainline builds have CONFIG_GOLDFISH_BUS=y, which causes "genirq: Flags mismatch irq 4. 00000000 (serial) vs. 00000080 (goldfish_pdev_bus)" and breaks serial. | 02:33 |
| apw | mamarley, yep, nothing which builds in yakkety works right now, the compiler changed to enable pie by default | 08:52 |

| mamarley | apw: How does it decide what to build on which distribution? | 10:09 |
| apw | mamarley, it is nominally version based. the nearest ubuntu distribution to the version it is trying to build | 10:10 |
| mamarley | Ah, OK. | 10:11 |
| apw | mamarley, more accuratly the configurations it uses are from the nearest ubuntu release tag it can find, and it builds in the same release that that configuration came from | 10:11 |
| mamarley | So this is the same bug that is preventing DKMS from compiling kernel modules on Yakkety? | 10:12 |
| apw | mamarley, yes the same one. DKMS should start working with the next copy forward kernel from X, as we have fixed it there) | 10:13 |
| apw | mamarley, but that does not fix mainline builds whihc also do not yet have that patch applied | 10:13 |
| apw | changing compiler defaults is bloody confusing to the world | 10:14 |
| apw | it is possible i can turn it off from outside, i've not yet tried that | 10:14 |
| mamarley | apw: While I've got you, it also looks like CONFIG_GOLDFISH_BUS is enabled in the 4.6 kernel configuration. I know I can't file a bug on it yet, but that driver attaches to the UART and breaks serial. | 10:17 |
| apw | mamarley, oh you can file a bug on it, indeed for something which breaks things a reason bug is always useful | 10:18 |
| mamarley | Ah, OK. I will do that then. | 10:18 |
| apw | if you do it now and tell me the number i'll get ti changed and then any reruns we do will have it off (for the mainline builds) | 10:18 |
| mamarley | apw: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1580960 | 10:26 |
| ubot5 | Ubuntu bug 1580960 in linux (Ubuntu) "Ubuntu-4.6.0-5.6 configuration has CONFIG_GOLDFISH and CONFIG_GOLDFISH_BUS enabled, breaking serial support on normal systems" [Undecided,New] | 10:26 |
| apw | well that is special we have CONFIG_X86_GOLDFISH off, and CONFIG_GOLDFISH which _depends_ on it and therefore cannot be y unless it is, is y | 10:42 |
| apw | which is kinda impossible in theory | 10:42 |
| apw | and yet is not impossible in practice apparenlty | 10:42 |
| mamarley | Yeah, it looked weird. It definitely breaks serial though. | 10:44 |
| mamarley | I guess the configuration will just need to manually specify "n" for all the goldfish stuff then? | 10:46 |
| apw | yep fixing it isn't the issue, trying to work out why the thing has not self-healed like it should | 10:48 |
| apw | mamarley, ok pushed for when i get the other fixes in | 10:52 |
| mamarley | Thanks :) | 10:52 |
| apw | i suppose i could switch all yakkety builds back to xenial or something in the interim | 10:54 |
| mamarley | apw: Yeah, that would at least keep them working for now. | 11:01 |
| apw | and my inbox full of people moaning they are on the wrong version | 11:01 |
| apw | then agian it is going to be full of people moaning they don't work anyhow | 11:01 |
| mamarley | Silly people :/ | 11:02 |
| * ricotz is happily using the 4.6 builds from kernel ppa with nvidia blob | 11:32 | |
| mamarley | Yeah, the -wily ones build amd64 and work fine, unless you have a device attached to a built-in serial port. That should be fixed for the next one though. | 11:32 |
| mamarley | And that should be this weekend, unless the switch from building on Yakkety to Xenial rebuilds the ones that have already been built. | 11:34 |
| mamarley | (Since 4,6 will be released officially this weekend, unless Linus changes his mind.) | 11:34 |
| apw | mamarley, i may have fixed the pie issue, am rebuilding a 4.6-rc7 to find out | 12:07 |
| mamarley | Thanks :) | 12:07 |
| apw | mamarley, and those rebuilds look better | 13:02 |
| mamarley | Yay! | 13:44 |
