[16:20] <sdeziel> while testing the retpoline enabled kernel ( linux-image-4.4.0-113-generic ) from xenial-proposed, I found a regression LP: #1748671 which I'd like to be fixed before this kernel hits -updates
[16:29] <sdeziel> oh, I just noticed linux-image-4.4.0-115-generic in -proposed, I'll see if it helps with the above bug
[16:32] <apw> sdeziel, do you know the last version that was not trivially reproduciblw
[16:32] <sdeziel> apw: 4.4.0-112.135 didn't have the issue
[16:33] <sdeziel> apw: it's what I had to roll back to
[17:09] <sdeziel> apw: 4.4.0-115.139 is also affected
[17:11] <apw> sdeziel, is that triggered by ipv6 in ipv4
[17:14] <sdeziel> apw: I don't know as the artful container tries to get both. I'll try to disable one and will report back. Unfortunately, the affected machine is this very laptop :(
[17:18] <sdeziel> apw: I just re-read an you said "ipv6 in ipv4" which I'm not using. Did you mean ipv6 OR ipv4 like I understood the first time?
[17:18] <apw> sdeziel, i had gotten the impression there was ipv6 in there
[17:19] <apw> sdeziel, this is 100% reproducible for you i believe right?
[17:19] <sdeziel> apw: yes, I'm assigning both v4 and v6 natively
[17:19] <sdeziel> yes, 100%
[17:19] <apw> sdeziel, as there is only one change in 112->113 for that sort fo thing, which has one fix since
[17:19] <apw> sdeziel, though that fix claims to be hyperthetical ... so ... hmmm
[17:20] <apw> sdeziel, so ... if you can test them I will throw both those options up for you
[17:20] <sdeziel> apw: sure, I'm here to test stuff :)
[17:22] <apw> sdeziel, amd64 ?
[17:22] <sdeziel> apw: yes
[17:23] <sdeziel> apw: "net: ipv4: fix for a race condition in raw_sendmsg" ?
[17:24] <apw> right ... whcih is also where your stack strace is in
[17:24] <apw> sdeziel, ^ will have something to test in about 20m
[17:25] <sdeziel> apw: awesome thanks
[17:26] <sdeziel> apw: I don't want to cloud the picture but I also hit LP: #1748513 with a similar looking trace to my untrained eye. It's on a different machine and not easily reproducible but maybe they both are related?
[17:47] <apw> sdeziel, ok i think we may have found an issue here which would explain the issue ... so could you test: http://people.canonical.com/~apw/lp1748671/fix-not-xenial/
[17:48] <sdeziel> apw: sure, give me a couple of minutes
[18:15] <apw> sdeziel, and don't forget the linux-image-extra
[18:15] <sdeziel> apw: no I won't :)
[18:19] <sdeziel> apw: I'm missing linux-signed-image-4.4.0-115-generic (https://paste.ubuntu.com/=wFyMVxCK2G/). Not sure if it matters
[18:20] <sdeziel> rebooting
[18:20] <apw> sdeziel, yeah i didn't make one, i can't make one with a signature that you could boot anyhow
[18:24] <sdeziel> apw: the test kernel fixed the problem
[18:25] <sdeziel> thanks a lot!
[18:26] <apw> sdeziel, ok great, will get that applied
[18:26] <sdeziel> apw: any idea if that could also fix LP: #1748513?
[21:16] <FjodorAE> Was looking forward to vboxguest module with 4.16, yet config patch seems to suggest it isn't set (config based on 4.15) - is someone aware, or where should I file a report?
[21:26] <apw> FjodorAE, file a bug against the package linux for now, and let me know the bug number
[21:41] <FjodorAE> apw: Thank you - https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1749015
