[12:29] Hi all, I'm trying to install ubuntu on my new pc with skylake i5-6600K processor, but starting the live cd immediately gives a kernel panic (caps + scroll lock blinking). Any advice on how to proceed? [12:31] need to see what the panic is [12:42] hm, now it suddenly works, at least the live system. Weird [12:47] After installing I get the following: Kernel panic: not syncing: Not all CPUs entered broadcast exception handler [12:49] that's a new one; what were the messages just before that? [12:52] [drm] failed to retreive link info, disabling eDP [12:53] [drm] initialised i915 1.60 20150731 for 000:00:02.0 on minor 1 [12:53] Kernel panic - Not syncing: Timeout: Not all CPUs entered broadcast exception handler [12:53] Shutting down cpus with NMI [12:55] yeh you need to report that; it shouldn't happen - I doubt the drm messages are related [12:56] I can report a bug from the live system, I just installed the system from there. Any idea what parameters I should pass the installed system to work around this? [12:57] no, never seen that one - what CPU do you have? [12:59] i5-6600k [12:59] nothing too odd then [13:00] reasonably odd as in very new, should be a skylake? [13:01] yes, its a skylake. Thats why I'm using xenial, as I read its not supported on earlier versions of ubuntu [13:01] xenial still has 4.3 kernel [13:01] probably should support it but might still have problems [13:02] lack of support is more normally just not using new features or stuff with graphics and things; it's a bit rare for it to panic that early on a new x86 [13:02] I'd try a 4.4 kernel if that does not work a bugreport is likely required [13:03] it's a shame that the xenial installers aren't using 4.4 already; 4.3 is broken on this machine (just graphics) [13:04] jtaylor: so install xenial on another drive, update it to -proposed, then put the drive in the skylake machine and see if it works? Or is there a smarter way to do that? [13:04] hm yes getting 4.4 installed without an existing working install may be tricky [13:05] mind you the fact the installer is booting for k6600 but not the installed is curious [13:08] penguin42: its on and off. Out of 4 tries, I was able to boot to the live system only once. Very weird [13:09] Is there a date for 4.4 to land in xenial? It's not on the release schedule [13:10] I don't think 4.4 has made it out of rc yet [13:19] Happy New Year folks [13:19] So what should I do? I want to get this fixed for myself, and also other users of 16.04 [13:19] HNY BluesKaj [13:20] k6600: You said you get about a 1/4 try success on the live system - is that true of the installed system? [13:20] hey penguin42 [13:25] penguin42: 1/4 was optimistic, I've got in only once now, for 10 kernel panics. I'll try the installed system next [13:26] k6600: If you can get the installed system to boot, once, then you can download and install the daily build of the 4.4 kernel [13:38] I'm in the installed system now, by using advanced settings -> upstart in grub. [13:41] k6600-installed: OK, 1st report the bug using ubuntu-bug kernel (it's either kernel or linux I can't remmber which) [13:41] k6600-installed: Then grab the daily kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ install that, reboot and hope for the best [13:42] bug 1530441 [13:42] bug 1530441 in linux (Ubuntu) "Kernel panic when booting" [Undecided,New] https://launchpad.net/bugs/1530441 [13:43] * penguin42 is suspicious what the choice of that advanced option did [13:44] still, lets see if 4.4 helps [13:44] k6600-installed: It'll be the http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/linux-image-4.4.0-999-generic_4.4.0-999.201512302100_amd64.deb you need [13:44] penguin42: thats just a menu option in grub, that hides older kernels, recovery mode and apparently also (upstart) in xenial [13:45] installing it now [13:46] k6600-installed: Yeh but I'm curious if you're hitting a fault like that early on from the kernel, why selecting upstart would make any difference [13:46] k6600-installed: Is this brand new hardware that's not run anything successfully yet? [13:47] it has been running windows 10 for a month now, mostly games, without issue [13:47] ok, good, so it's probably not hardware [13:47] I've also updated the bios and ran memtest for a single pass [13:47] ok good, updating the bios was the other thing I was going to suggest; but yes that makes sense [13:49] here goes the reboot, brb [13:49] I'm not normally that worried about the bios, but when it's new CPUs/motherboard they sometimes haven't got the kinks out of it yet [13:52] it works [13:53] wahey! [13:53] k6600-installed: Please add a comment to your bug about the version it works on [13:58] penguin42: added. Do I have to remove this kernel when 4.4 becomes available on xenia or will it have the version in the repo have a higher version number? [13:58] k6600-installed: Hmm I'm not sure; I think you might need to remove it [14:00] I'll keep an eye out for when 4.4 lands, I'll probably have to reinstall anyway after using the pre-release ubuntu for a few months [14:02] Thanks a lot for your help, I'm happy I finally have ubuntu running on my brand new pc ;) [15:56] anyone go a sign of alpha 1 yet, just upgraded bit nothing much changed [15:57] there is no real change. its more of a milestone [15:58] k1l_: ok tnx, so its just a name of a step forward? [16:23] yep [16:24] a mark on the railroad. some things need to be worked out until that mark [16:24] k1l_: when will we start seeing real changes apply then? before final i hope? [16:24] https://wiki.ubuntu.com/XenialXerus/ReleaseSchedule [16:27] I'd assume being an LTS they wont try and squish vast numbers of features in [16:28] penguin42: what do you mean [16:28] penguin42: alot of articles showed already upcomming new xenial features [16:31] lotuspsychje: Well for an LTS you'd hope it would be stable and well tested, not a massive new feature thrown in at the last minute - you'd hope [16:31] new plymouth, new startup disk creator, dock to bottom,online search vanish from dash,... [16:31] when will all those packages arrive on final? [16:31] dock to bottom? [16:31] k1l_: ye left unity bar to bottom ive read mate [16:32] where? [16:32] lemme find that article holdon [16:34] k1l_: http://linux.softpedia.com/blog/ubuntu-16-04-lts-to-let-users-move-the-unity-launcher-at-the-bottom-of-the-screen-498000.shtml [16:39] gnome software :p [16:39] its gonna be interesting release : === lotuspsychje_ is now known as lotuspsychje [22:32] Im thinking of updating from 14.04 to 16.04 alpha. DO I just write sudo do-release-upgrade -d ? [22:36] yes. make sure the upgrade path is set to LTS [22:41] k1l_, I ave a problem. It says i need 81 mb free in boot [22:41] k1l_, http://paste.ubuntu.com/14363152/ <- that is ls boot [22:41] What can i remove? [22:41] I think my boot is about 100 mb [22:42] what? hta tis way to small. [22:44] k1l_, If i remove everything thats enough for 81 mb :S [22:44] I think my boot is like 100 b [22:44] mb [22:44] first solve the issue that your /boot partition is way to small. [22:44] that will make trouble all the time [22:44] k1l_, No, its 200 mb [22:44] I think maybe its a hidden trash there [22:45] ls -alh [22:46] Ok, i had to delete the trash file that was hidden. Now it starts , hopefully it will work [23:42] Hi. People tell me Alpha1 has been released but I cannot find a specific download page for it. Is it just the latest daily build? Thanks! [23:45] https://lists.ubuntu.com/archives/ubuntu-release/2015-December/003483.html [23:46] i would use the daily builds so far [23:49] Ok. Thanks.
