[11:07] <caribou> morning, is there a 'trick' in the kernel build sequence to avoid changing the ABI during the build ?
[11:07] <caribou> I'm trying to only rebuilt the bzImage for a kernel bissect w/o rebuilding all the modules
[11:09] <caribou> Is forcing ABINUM in debian/rules sufficient ?
[11:11] <apw> caribou, what are you doing, adding a patch oro something ?
[11:12] <caribou> apw: just bissecting b/w two kernel version (4.7 <-> 4.8) to identify a problematic commit
[11:12] <apw> slam skipabi=true skipmodule=true (or is that skipmodules=true) on the build
[11:13] <caribou> apw: ok, will try that
[11:59] <robertfoss> apw: ^
[12:00] <apw> robertfoss, ?  (assume i have the memory of a goldfish on Temazepam
[13:35] <robertfoss> apw: you mentioned some kernel patches to get it compiling with gcc 6.2
[13:35] <apw> oh that, i think i mentioned to work with pie, but i think we are using gcc5 for kernels
[13:37] <mamarley> I haven't tried the regular kernel in a while, but the mainline kernels are still compiled with GCC 6.  I know the 4.4 kernel that was in Yakkety for a while was compiled with GCC 5 though.
[13:38] <robertfoss> mamarley, apw: I just ran a git clone from trunk on a 16.10 box, but it does not compile due to PIE/PIC issues
[13:41] <apw> https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/yakkety/commit/?id=d0fb5a1973caeb761d82f5a863b139e23e7f0671
[13:41] <apw> robertfoss, might be that one, that is meant to be making its way upstream from the author
[13:44] <robertfoss> apw: thank you! I'll check it out
[16:02] <michael-vb> Hello all.  Sorry for this hit-and-run reporting (have to move fast, but will stay logged in).
[16:02] <michael-vb> I reported a couple of days ago that recent daily builds did not work in a 32-bit VirtualBox VM - the first modeset happens after grub, but the first kernel message does not.
[16:02] <michael-vb> Wanted to say that 4.9.0rc1 still shows the same.
[16:03] <michael-vb> (Afk, but will read the scroll-back later.)
[16:38] <jacalope> Hello folks, I'm having a perpetual kernel panic after trying to return from suspend in my Samsung laptop using (K)ubuntu: http://paste.ubuntu.com/23339007/
[16:40] <jacalope> 4.4.0-* kernels panic, but if I go back to 4.2.0-38-generic, I can get in.
[16:41] <jacalope> The link is where I booted with a liveusb and got dmesg and dump files from var/crash -> http://paste.ubuntu.com/23339007/
[16:42] <jacalope> Using 16.04
[16:44] <apw> jacalope, that looks like a very unhappy wireless driver or something like that
[16:44] <apw> jacalope, if you file an actual bug we can do a bisection on that maybe
[16:44] <apw> jsalisbury, ^
[16:54] <jacalope> apw: thanks. I'm trying to work through filing it as a bug. First time doing that, so it's a bumbling process :)
[16:57] <jacalope> apw: Wait. Should I file with ubuntu/launchpad, or directly with linux/kernel?
[16:59] <apw> jacalope, i'd start with us, we cna tell you to do that if we cannot help
[17:00] <jsalisbury> apw, ack
[17:01] <jsalisbury> jacalope, from a terminal run this: ubuntu-bug linux
[17:04] <jacalope> jsalisbury: That returns a "the problem cannot be reported" dialog box from apport-- Of course I've booted using an older 4.2 kernel so its message makes sense to me. 
[17:05] <jacalope> Since the 4.4 kernel panicked, do I need to file bug another way?
[17:05] <jsalisbury> jacalope, you can also go directly to the launchpad web interface: 
[17:05] <jsalisbury> https://bugs.launchpad.net/ubuntu/+source/linux/+filebug
[17:24] <michael-vb> (Back briefly...) (18:02:37) michael-vb: Hello all.  Sorry for this hit-and-run reporting (...)
[17:24] <michael-vb> Would be interested if anyone knows more about that.
[17:27] <apw> michael-vb, with yakkey ?
[17:33] <michael-vb> Right.
[17:33] <michael-vb> 4.8.0 worked fine, everything I tried since 4.8.0-999 October 11 hung, including 4.9.0rc1.
[17:34] <michael-vb> (Really have to run, will stay logged in...)
[17:35] <apw> i guess i want to know what you mean by 4.8.0, is that the official yakkety kernels ?
[17:36] <apw> the others you are mentioning are mainline builds, so often don't work with corner cases
[17:55] <jacalope> jsalisbury: apw: I submitted a bug report regarding the kernel panic: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634214
[17:55] <ubot5`> Ubuntu bug 1634214 in linux (Ubuntu) "kernel panic on resume from suspend with 4.4.0 kernels" [Undecided,New]
[17:55] <jacalope> I did my best, if any more info is needed I am more than obliged to provide.
[17:59] <rtg> jacalope, try 'sudo modprobe -r iwlwifi' before you close the lid.
[18:00] <jacalope> rtg: will be happy to, but I can't get back into any of my 4.4 kernels at the moment
[18:00] <jacalope> that removes the wireless driver before suspending, right?
[18:01] <rtg> jacalope, right, looks like your wifi adapter is an older model (i2400), though I am still looking
[18:02] <rtg> is this really WiMAX ?
[18:05] <jacalope> It has WiMAX, yes, but I've never used that particular functionality
[18:06] <rtg> jacalope, that appears to be what is crashing.  Once you can get booted into a 4.4 kernel please attach the list of modules (lsmod)
[18:06] <jacalope> I've never really understood what the WiMAX is for, tbh. WiFi functionality has worked pretty well, except for the occasional > service network-manager restart trick
[18:07] <rtg> jacalope, WiMAX is a different kind of wireless, but it is sort of a failed technology
[18:07] <jacalope> Yeah, booting into 4.4 is the current issue. The system just hangs with the kernel panic. Is there a way around that?
[18:08] <rtg> jacalope, can you boot into an older kernel ? catch the boot process at the grub prompt ?
[18:08] <jacalope> Like, is there a locked file or something? Every 4.4 kernel I have is panicking, but the 4.2 lets me in. Seems odd to me since I've used 4.4 for months
[18:08] <jacalope> yeah, I can get into grub and 4.2
[18:09] <rtg> a 4.2 kernel should be fine for getting the modules list. you can also blacklist the i2400 driver once you've got a filesystem mounted.
[18:12] <jacalope> rtg: ok, I've attached the lsmod output to the bug report.
[18:14] <rtg> jacalope, ok, read up on http://askubuntu.com/questions/110341/how-to-blacklist-kernel-modules and blacklist i2400m and i2400m_usb.
[18:16] <rtg> jacalope, this also has some good tricks, especially at the end using the kernel command line: https://wiki.archlinux.org/index.php/kernel_modules
[18:18] <jacalope> ok, scanning now. Just to confirm, add the "blacklist xxxx" lines at the end of blacklist.conf? (There seem to be files specializing in some way, e.g. blacklist-modem.conf etc.)
[18:19] <apw> jacalope, you could make a like blacklist-jackalope.conf as long as it ends .conf
[18:30] <jacalope> ok, so I added my blacklist-jacalope.conf file (thanks for that btw) and rebooted into 4.2. lsmod doesn't report i2400m or i2400m_usb.
[18:30] <jacalope> However, 4.4 still seems to panic, or at leas the visual results appears the same
[20:11] <hans109h> can someone help explain why every 15 minutes my kernel log says kernel: [ 1682.088022]  sda:
