Package: src:linux Version: 4.19.12-1 Severity: important Hi!
After upgrading an i386 box (Soekris net5501) running testing (buster), I found out that the newly migrated Linux kernel fails to boot. Looking at the boot through the serial console reveals the attached output, in which I spotted the following line: [ 5.363599] kernel BUG at arch/x86/mm/pat.c:549! The previous kernel image (4.18.20-2) works with no issues. I have temporarily altered GRUB_DEFAULT in /etc/default/grub, in order to force the box to automatically boot that kernel version. I hope this bug may be fixed soon. Thanks a lot for any help you may provide! -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (800, 'testing'), (500, 'unstable') Architecture: i386 (i586) Kernel: Linux 4.18.0-3-686 (SMP w/1 CPU core) 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: sysvinit (via /sbin/init) LSM: AppArmor: enabled
