--- Begin Message ---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 -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing'), (2, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.14.0-2-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages apparmor depends on: ii debconf [debconf-2.0] 1.5.65 ii libc6 2.25-5 ii lsb-base 9.20170808 ii python3 3.6.4~rc1-2 apparmor recommends no packages.
