[12:29] <k6600> 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] <ikonia> need to see what the panic is
[12:42] <k6600> hm, now it suddenly works, at least the live system. Weird
[12:47] <k6600> After installing I get the following: Kernel panic: not syncing: Not all CPUs entered broadcast exception handler
[12:49] <penguin42> that's a new one; what were the messages just before that?
[12:52] <k6600> [drm] failed to retreive link info, disabling eDP
[12:53] <k6600> [drm] initialised i915 1.60 20150731 for 000:00:02.0 on minor 1
[12:53] <k6600> Kernel panic - Not syncing: Timeout: Not all CPUs entered broadcast exception handler
[12:53] <k6600> Shutting down cpus with NMI
[12:55] <penguin42> yeh you need to report that; it shouldn't happen - I doubt the drm messages are related
[12:56] <k6600> 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] <penguin42> no, never seen that one - what CPU do you have?
[12:59] <k6600> i5-6600k
[12:59] <penguin42> nothing too odd then
[13:00] <jtaylor> reasonably odd as in very new, should be a skylake?
[13:01] <k6600> yes, its a skylake. Thats why I'm using xenial, as I read its not supported on earlier versions of ubuntu
[13:01] <jtaylor> xenial still has 4.3 kernel
[13:01] <jtaylor> probably should support it but might still have problems
[13:02] <penguin42> 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] <jtaylor> I'd try a 4.4 kernel if that does not work a bugreport is likely required
[13:03] <penguin42> 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] <k6600> 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] <jtaylor> hm yes getting 4.4 installed without an existing working install may be tricky
[13:05] <penguin42> mind you the fact the installer is booting for k6600 but not the installed is curious
[13:08] <k6600> penguin42: its on and off. Out of 4 tries, I was able to boot to the live system only once. Very weird
[13:09] <k6600> Is there a date for 4.4 to land in xenial? It's not on the release schedule
[13:10] <penguin42> I don't think 4.4 has made it out of rc yet
[13:19] <BluesKaj> Happy New Year folks
[13:19] <k6600> So what should I do? I want to get this fixed for myself, and also other users of 16.04
[13:19] <penguin42> HNY BluesKaj
[13:20] <penguin42> k6600: You said you get about a 1/4 try success on the live system - is that true of the installed system?
[13:20] <BluesKaj> hey penguin42
[13:25] <k6600> 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] <penguin42> 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] <k6600-installed> I'm in the installed system now, by using advanced settings -> upstart in grub.
[13:41] <penguin42> k6600-installed: OK, 1st report the bug using ubuntu-bug  kernel   (it's either kernel or linux I can't remmber which)
[13:41] <penguin42> 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] <k6600-installed> bug 1530441
[13:43]  * penguin42 is suspicious what the choice of that advanced option did
[13:44] <penguin42> still, lets see if 4.4 helps
[13:44] <penguin42> 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] <k6600-installed> penguin42: thats just a menu option in grub, that hides older kernels, recovery mode and apparently also (upstart) in xenial
[13:45] <k6600-installed> installing it now
[13:46] <penguin42> 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] <penguin42> k6600-installed: Is this brand new hardware that's not run anything successfully yet?
[13:47] <k6600-installed> it has been running windows 10 for a month now, mostly games, without issue
[13:47] <penguin42> ok, good, so it's probably not hardware
[13:47] <k6600-installed> I've also updated the bios and ran memtest for a single pass
[13:47] <penguin42> ok good, updating the bios was the other thing I was going to suggest; but yes that makes sense
[13:49] <k6600-installed> here goes the reboot, brb
[13:49] <penguin42> 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] <k6600-installed> it works
[13:53] <penguin42> wahey!
[13:53] <penguin42> k6600-installed: Please add a comment to your bug about the version it works on
[13:58] <k6600-installed> 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] <penguin42> k6600-installed: Hmm I'm not sure; I think you might need to remove it
[14:00] <k6600-installed> 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] <k6600-installed> Thanks a lot for your help, I'm happy I finally have ubuntu running on my brand new pc ;)
[15:56] <lotuspsychje> anyone go a sign of alpha 1 yet, just upgraded bit nothing much changed
[15:57] <k1l_> there is no real change. its more of a milestone
[15:58] <lotuspsychje> k1l_: ok tnx, so its just a name of a step forward?
[16:23] <k1l_> yep
[16:24] <k1l_> a mark on the railroad. some things need to be worked out until that mark
[16:24] <lotuspsychje> k1l_: when will we start seeing real changes apply then? before final i hope?
[16:24] <k1l_> https://wiki.ubuntu.com/XenialXerus/ReleaseSchedule
[16:27] <penguin42> I'd assume being an LTS they wont try and squish vast numbers of features in
[16:28] <lotuspsychje> penguin42: what do you mean
[16:28] <lotuspsychje> penguin42: alot of articles showed already upcomming new xenial features
[16:31] <penguin42> 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] <lotuspsychje> new plymouth, new startup disk creator, dock to bottom,online search vanish from dash,...
[16:31] <lotuspsychje> when will all those packages arrive on final?
[16:31] <k1l_> dock to bottom?
[16:31] <lotuspsychje> k1l_: ye left unity bar to bottom ive read mate
[16:32] <k1l_> where?
[16:32] <lotuspsychje> lemme find that article holdon
[16:34] <lotuspsychje> 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] <lotuspsychje> gnome software :p
[16:39] <lotuspsychje> its gonna be interesting release :
[22:32] <lrs> Im thinking of updating from 14.04 to 16.04 alpha. DO I just write sudo do-release-upgrade -d ?
[22:36] <k1l_> yes. make sure the upgrade path is set to LTS
[22:41] <lrs> k1l_, I ave a problem. It says i need 81 mb free in boot
[22:41] <lrs> k1l_, http://paste.ubuntu.com/14363152/ <- that is ls boot
[22:41] <lrs> What can i remove?
[22:41] <lrs> I think my boot is about 100 mb
[22:42] <k1l_> what? hta tis way to small.
[22:44] <lrs> k1l_, If i remove everything thats enough for 81 mb :S
[22:44] <lrs> I think my boot is like 100 b
[22:44] <lrs> mb
[22:44] <k1l_> first solve the issue that your /boot partition is way to small.
[22:44] <k1l_> that will make trouble all the time
[22:44] <lrs> k1l_, No, its 200 mb
[22:44] <lrs> I think maybe its a hidden trash there
[22:45] <k1l_> ls -alh
[22:46] <lrs> Ok, i had to delete the trash file that was hidden. Now it starts , hopefully it will work
[23:42] <hjtbk> 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] <k1l_> https://lists.ubuntu.com/archives/ubuntu-release/2015-December/003483.html
[23:46] <k1l_> i would use the daily builds so far
[23:49] <hjtbk> Ok. Thanks.
