[08:20] <apw> djs, given the only thing you change is the kenrnel, that tends to indicate it is related to that rather doesn't it ?
[09:58] <ddalex> hi
[09:59] <ddalex> I'm getting errors with a ppa/mainline kernel
[09:59] <ddalex> where should I report them ?
[10:00] <ddalex> or, maybe, how ?
[10:03] <apw> ddalex, those are debugging tools, so mostly not supported, we may be interested in some classes of issues as they may indicate issues coming down the line
[10:04] <ddalex> apw, are these unmodified upstream kernels ? i.e. are the bug reports valid for bugzilla.kernel.org ?
[10:04] <apw> they are unmodified indeed, they have an ubuntu-like configuration applied but otehr than that no changes
[10:04] <apw> ddalex, so yes filing them upstream is not unreasonable
[10:05] <ddalex> thanks, I'll fill upstream

[12:11] <ogasawara> zyga: thanks!
[13:27] <attente> does building the kernel require editing the Makefiles to disable -pie? is there some easier way to pass cflags into the build system?
[13:29] <apw> attente, which series are you building on, and which kernel are you trying to build.  depending on the combinations that can be true
[13:29] <apw> attente, though there is a patch in recent ubuntu kernels for that
[13:30] <attente> apw: building from git://kernel.ubuntu.com/ubuntu/ubuntu-yakkety.git
[13:31] <attente> apw: it's the current master with a small patch on top
[13:31] <attente> Ubuntu-4.4.0-22.40
[13:32] <apw> attente, right but what are you building that _on_ as a local host, you should be building it in a
[13:32] <apw> yakkety chroot, whcih wuold understand the pie bits
[13:33] <apw> though -22 is very old, why that one of all of them, maybe that is too old to have the fix
[13:33] <attente> apw: which branch is the development target?
[13:34] <apw> for the 4.4 that is in the xenial repositories, we're working on 4.6 in the yakkety repo
[14:44] <djs> apw: well, yes, the failure to decrypt the rootfs is definitely related to the kernel since that is the only thing changing
[14:45] <djs> apw: I'm wondering whether it's a timing problem of some sort, I was poking through the initramfs-tools scripts a bit trying to see where it might be getting stuck
[14:46] <djs> but so far no luck... booting with debug doesn't get me anywhere, the problem is earlier than that
[14:47] <apw> djs, it was 4.7 you were trying out wasn't it
[14:48] <djs> yeah
[14:48] <apw> i would guess we have something useful turned off in that 4.7 build, like an encryption algo or something
[14:50] <djs> yeah possibly... I was also looking over diffs between the 4.6.4 and 4.7.0 initrd and there definitely are some
[14:50] <djs> so do those builds get refreshed from time to time or are they static?
[14:53] <apw> builds are a one off, unless we find a clear config issue which gets fixed in our main branches, then i may chose to respin them
[14:54] <djs> ok, so do you have any suggestions on how I ought to proceed? my interest in newer kernels is support for newer hardware in the laptop I'm running on
[14:54] <djs> it's not too bad with 4.6.4 but I'm hoping a few issues will be fixed with 4.7
