slangasekjsalisbury: e63a94f12b5fc67b2b92a89d4058e7a9021e900e is good00:10
slangasekjsalisbury: so that's a merge commit, and 'git bisect' stops there for me?00:12
jsalisburyslangasek, Yeah, your right.  The bisect usually goes down into a merge, but it isn't in this case.  00:14
jsalisburyslangasek, I'll look at that merge and see if there are commits in it that stuck out and could be the fix00:14
jsalisburyslangasek, If nothting sticks out, I can manually bisect in that merge I suppose.00:15
slangasekjsalisbury: k.  it's "only" 105 commits on the tty stack, 4kloc :)00:15
jsalisburyslangasek, heh, yeah00:15
jsalisburyslangasek, I hate when bisects don't have a easy and happy ending.  I'll let you know when a kernel is ready.  May not be until the morning though.00:17
slangasekjsalisbury: no problem00:18
slangasek979990c6284814617d8f2179d197f72ff62b5d85 looks vaguely interesting00:19
slangasekby and large, the merge commit's description of being "mostly serial" is supported by the commit log00:20
jsalisburyslangasek, that was cc'd to stable, so it's on its way to us anyway.  I could build a test kenel with it just for the heck of it.00:22
jsalisburyslangasek, if you want to test it out, I built an Artful kernel with a pick of commit 979990c6284814617d8f2179d197f72ff62b5d8501:22
jsalisburyslangasek, if that's not it, I'll dig further into that merge01:23
slangasekjsalisbury: that one didn't do the trick either :/03:09
jsalisburyslangasek, I'll look at that merge closeer and manually bisect it if needed.11:15
apwjsalisbury, is there any reason you canont just start a new bisct between the first commit on the branch and the git mergebase of the two parents of the merge ?11:18
jsalisburyapw, I'll give that a try.  I'm not sure whey the bisect didn't go down into the merge.11:55
apwno indeed that is idd11:56
TJ-maybe it was an octopus merge (3 or more branches at once) ?11:59
jsalisburyTJ-, maybe.  apw, it looks like your method shoudl work12:02
jsalisburyslangasek I started a new "Reverse" bisect of just the merge using:12:11
jsalisbury# good: [1a3b85ea36d38d5732fdd86b321b10bcaeb53512] Merge tag 'usb-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb12:11
jsalisbury# bad: [3840ed9548f778717aaab5eab744da798c3ea055] tty: goldfish: Implement support for kernel 'earlycon' parameter12:11
jsalisburyI built the first test kernel, up to the following commit:12:11

=== cachio is now known as cachio_lunch

jsalisburyslangasek, thanks, I'll build the next one.18:00

jsalisburyslangasek, ack. I'll build the next one18:44
jsalisburyslangasek, test kernel up to commit cdb939456f81878cda1f31ba0ef1a3b1d7be07e8 is ready.18:54
slangasekjsalisbury: cdb939456f81878cda1f31ba0ef1a3b1d7be07e8 bad19:57
jsalisburyslangasek, ack, building the next one20:08
jsalisburyslangasek, commit 2ce8008711e4837c11e99a94df55406085d0d098 is ready.20:18
slangasekjsalisbury: 2ce8008711e4837c11e99a94df55406085d0d098 bad21:14
jsalisburyslangasek, ack, I'll build the next one21:14
jsalisburyslangasek, commit d01c3289e7d68162e32bc08c2b65dd1a216a7ef8 is ready.21:25
slangasekjsalisbury: not visible on http://kernel.ubuntu.com/~jsalisbury/lp1724911/ 21:29
jsalisburyslangasek, sorry, should be there now.21:44
slangasekjsalisbury: looks good, thanks21:47
slangasekjsalisbury: d01c3289e7d68162e32bc08c2b65dd1a216a7ef8 bad22:14
jsalisburyslangasek, ack22:15
jsalisburyslangasek, commit ae28d7402a7e7cf3dd0da1f2eb6a52b337873e08 is ready22:38
slangasekjsalisbury: eventually one of these kernels is going to be good again, right? :) ae28d7402a7e7cf3dd0da1f2eb6a52b337873e08 bad23:26
slangasekjsalisbury: so I went back to the bug log and noticed you listed your bisect as between 1a3b85ea36d38d5732fdd86b321b10bcaeb53512 and 3840ed9548f778717aaab5eab744da798c3ea055 but both of those commits were bad23:28
jsalisburyslangasek, hmm, I must have gotten the merge commits wrong from e63a94f12b.  I'll investigate a bit and ask apw if I can't figure it out.23:51
