Package: apparmor
Version: 2.11.1-4
Severity: important
Dear Maintainer,
* What led up to the situation?
Installed kernel 4.14 in Debian Testing and ever since at every upgrade
where systemd or other important
packages were upgraded the system froze with the last 2 lines in the
system log:
Dec 29 21:25:26 laca-desktop kernel: BUG: unable to handle kernel NULL
pointer dereference at 0000000000000005
Dec 29 21:25:26 laca-desktop kernel: IP: __task_pid_nr_ns+0xc7/0xf0
The system became unresponsive, not even the sysrq combinations were
working
* What exactly did you do (or not do) that was effective (or
ineffective)?
Restarted ran dpkg --configure -a and every time the system froze
Booting with the 4.13 kernel was fine, dpkg finished its run
At the next upgrade i still got the freeze, after reboot i disabled the
kernel security features with the kernel command line security=false
* What was the outcome of this action?
dpkg was working fine with the kernel 4.14 too
