Docker crashes Linux-ck

Hi all,

I know this is either Docker or Linux-ck problem, but before trying to reach to them, i wonder what fellow Achers have to say.

Docker works fine with a stock kernel, but crashes kernel with -ck patches. Here is the problem:

1) When i enable docker like this - systemctl enable docker - i can't boot into Linux-ck at all, facing this crash:

2) When i disable docker, i can boot fine and actually i can even use docker after starting it manually - systemctl start docker. It works fine, but when i shut down or reboot, i observe a similar crash. It doesn't matter whether i stopped docker or not, the kernel will crash:

Some information:

$ uname -a
Linux laptop 4.10.10-1-ck-ivybridge #1 SMP PREEMPT Wed Apr 12 16:52:01 EDT 2017 x86_64 GNU/Linux

$ cat /sys/block/*/queue/scheduler
noop deadline cfq [bfq]
noop deadline cfq [bfq]
noop deadline cfq [bfq]

$ dmesg | grep "CPU scheduler"
[    2.374786] MuQSS CPU scheduler v0.152 by Con Kolivas.

$ docker --version
Docker version 17.04.0-ce, build 4845c567eb

Looking forward to your replies.

Will do that..  Meanwhile, changing io scheduler from bfq to noop resolved crashes.

Don't post images of text, paste the actual text. And read the Code of Conduct and only post thumbnails http://wiki.archlinux.org/index.php/Cod … s_and_code

Re: Docker crashes Linux-ck

Do you happen to know how to copy text from kernel panic screen?
Making image a thumbnail size is a good idea, though.

Re: Docker crashes Linux-ck

There has been commits to the bfq scheduler on github which also includes a use after free fix. I've been running my kernel with that patch without any issues. You might give it a try.
