esnyderhi all. i'm struggling to get crashdump working on ubuntu 13.10 running as a virtualbox guest on a mac. trying to follow https://wiki.ubuntu.com/Kernel/CrashdumpRecipe00:53
esnyderi found someone having similar problems at https://bugs.launchpad.net/ubuntu/+source/kexec-tools/+bug/123561600:53

esnyderanyone have advice for me? should this work, and i need to just keep futzing, or are there known issues?00:54

apwsmb, so i have simple-f cause i am on -511:44
apwE: DRIVER=simple-framebuffer11:44
apwi'd not see that if i updated you say yes ?11:44
smbapw, yep11:44
apwthen all is good11:44
smbapw, It was the updated kernel that caused me to fight efi-framebuffer (as simple was gone)11:45
apwahh heh11:45
apwanyhow when that version hits, i would like to know if that works ok on your radeon box11:46
apwor whether i need to fix vesafb11:46
smbapw, So I ran with that changed locally and this makes vesafb still load but the idev event has not the primary env var set11:48
smbprobably what we expect11:49
smbStill comes up, got that weird login bug again... but that could be fluke11:49
apwwell thats something12:08
apwrsalveti, hey ... mako, we have just gotten a security team patch set for this kernel, but there is a version just sitting in our PPA for your testing, shuld i just replace it and we reset from there or do you want to do something with it first12:11
smbapw, So a qemu uri for virsh is "virsh -c qemu+ssh://<user>@<host>/system12:24
rsalvetiapw: better to just replace it with the security fix, and rebase the tree with the current changes12:38
rsalvetiapw: as we're not done yet with android 4.412:39
apwrsalveti, this is bringing in yama not a security fix, so i don't need to drop it on wahts in the archive at all12:42
apwrsalveti, i was more thinking shall i update the 4.4 version in the PPA with it12:42
rsalvetiapw: oh, then yeah12:42
rsalvetithat would be better12:42
rsalvetiand easier12:42
apwok ... thanks will do that12:42
rtgjjohansen, I don't think the config patch for bug #1270215 is doing the right thing according to the bug reporter.13:17

bjfrtg, no, but it tells you that the tests ran to completion and results got posted13:54

DW-10297Does anybody know if the kernel in the netboot package for 12.04.4 will finally have support for the Intel I210/I217 NICs?14:10
DW-10297those drivers have been available forever14:11
DW-10297That would make life soo much easier for folks that have gigantic clusters of boxes with those NICs in them14:13
apwDW-10297, if you can tell us what the driver for that is, we can check14:14
rtgindeed, we ought to be able to netboot an Intel NIC14:17
DW-10297yeah when those nics came out 18 months ago i requested this and i was told to shove it =D14:17
DW-10297and several releases of the netboot package came and went14:18
apwDW-10297, did you file a bug about it?14:18
apwand if so what was the number, so i can see what happeneed to it14:18
apwit might have been helpful to test the beta images a couple of weeks ago, then we could have made sure14:19
DW-10297Intel(R) PRO/1000 Network Driver - 2.1.4-k in 13.04 sees the target NICs14:20
apwwhat does lsmod say is bound to it14:20
DW-10297it says used by 014:21
DW-10297but in dmesg when the kernel starts its indicating that it's using that driver for the NIC14:22
DW-10297on a supermicro server board that has Intel Corporation I210 Gigabit (lspci) it uses igb 5.0.5-k (in centos)14:25
DW-10297so i guess as long as it has at least 2.1.4-k of e1000e and igb 5.0.5-k (or whatever) it should work fine14:26
DW-10297by the way here is the bug that someone else filed for this a lonnggg time ago14:27
ubot2`Launchpad bug 1182878 in linux (Ubuntu) "i210/i217 unsupported by igb / e1000e driver in precise" [Medium,Invalid]14:27
DW-10297and it was marked invalid14:27
DW-10297for no reason14:27
=== ghostcube_ is now known as ghostcube
DW-10297apparently this should've been fixed in 12.04.314:31
DW-10297but i can confirm it doesnt work14:32
DW-10297at least not in the netboot kernel14:32
DW-10297even the jan 10 release of the netboot package14:32
bjfDW-10297, according to comment 7 of that bug, the person that filed the bug says it is working for him and it's no longer valid14:34
DW-10297it might work if you install it from a cd14:34
bjfDW-10297, that was done june of last year. if you disagreed, you could have commented on the bug or opened your own14:35
rtgDW-10297, it would sure help if you would start a bug and attach a dmesg to it so we can start looking at some specifics. Intel typically has really good support for their drivers.14:35
DW-10297its not a problem with intel's drivers, it's that the kernel in http://archive.ubuntu.com/ubuntu/dists/precise-updates/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/ doesn't have the right driver14:36
rtgDW-10297, a 3.2 kernel likely _won't_ have the right driver. if you have the same HW as in bug 1182878, then you'll need at least a 3.5 kernel, i.e., 12.04.214:39

DW-10297rtg: Okay, i'm not arguing that. I'm trying to figure out why the netboot images aren't kept up to date with whats going on in the actual kernel14:39
DW-10297I asked #ubuntu-installer, they told me to ask you guys14:40
rtgDW-10297, ok, I'm just researching that. I admit I've never net booted 12.04.214:40
rtgin fact, I rarely netboot at all14:40
DW-10297its slightly useful in clouds14:40
DW-10297I just found it odd that there was just a new release of ubuntu installer netboot on Jan 10 and it still didnt include support for Haswell14:44
rtgDW-10297, I'm sure there is a way to do it, but it may require you to configure your own Cobbler or MAAS servers14:44
apwit is likely missing from the d-i configuration, the upstream peeps just love to change the names of their drivers for shits and giggles, and then they get lost14:44
DW-10297I think Debian 7 may actually have the driver in their installer as well. I can check if it helps14:46
DW-10297anyway I will just cross my fingers and hope that the 12.04.4 netboot works =D14:48
apwif you could test that and if it does not file a bug against 'linux' (ubuntu-bug linux) and put all the details in it, which driver it is using etc then we might be able to fix it14:49
DW-10297i will just see if 12.04.4's install fixes it first, if not i'll try it on debian and see how that goes14:50
DW-10297.4 should be out sometime soon i would hope14:50
bjfDW-10297, today is the release day for .414:51
bjfDW-10297, and why a bug report before today would have been helpful14:51
DW-10297yeah I knew that but i didnt want to be like.. if they ever publish it to the mirrors haha =)14:52
DW-10297I guess I just assumed that it would make sense to refactor the kernels used in the installer every once in awhile to add new drivers14:52
DW-10297even RHEL does that14:52
