** Description changed:
This came up in snapd spread tests but can be reproduced with:
In an i386 up to date 16.04 VM:
1. in one terminal, run this:
- $ cat changehat_reproducer.sh
+ $ cat reproducer.sh
#!/bin/sh
set -e
sudo sysctl -w kernel.printk_ratelimit=0
sudo snap install hello-world || true
count=0
while /bin/true ; do
- count=$((count+1))
- if [ `echo "$count % 100" | bc` -eq 0 ]; then
- echo "$count runs"
- fi
- hello-world > /dev/null || {
- tail -100 /var/log/syslog | grep DEN && exit
- }
- sudo cat /run/snapd/ns/hello-world.mnt 2>/dev/null || sudo
/usr/lib/snapd/snap-discard-ns hello-world
+ count=$((count+1))
+ if [ `echo "$count % 100" | bc` -eq 0 ]; then
+ echo "$count runs"
+ fi
+ hello-world > /dev/null || {
+ tail -100 /var/log/syslog | grep DEN && exit
+ }
+ sudo cat /run/snapd/ns/hello-world.mnt 2>/dev/null || sudo
/usr/lib/snapd/snap-discard-ns hello-world
done
2. in another terminal run:
$ while do /bin/true ; sudo apparmor_parser -r /etc/apparmor.d/* >/dev/null
2>&1 ; done
3. In another terminal:
$ tail -f /var/log/syslog|grep DEN

This is not limited to i386.
