Package: systemd Version: 232-18 Severity: normal Dear Maintainer,
I upgraded to stretch, using kernel 4.4.47. When rebooting, system could not clean up device mapper targets, leading to a hard crash for all cache targets, requiring many hours of heavy I/O after bootup and creating a high-risk window for data corruption. The specific error I got was something like (from memory): Could not detach DM dm-11: ioctl mismatch, kernel(4.34.4), user(4.35.4) Since kernel 4.4 was until very recently the newest longterm stable kernel and 4.9 has many issues (most notably btrfs losing files), it would be extremely appreciated if 4.4 would still be supported in stretch, at least until the newer kernel versions stabilise. Alternatively, since lvm and dmsetup from stretch do not have any issues with kernel 4.4, I suspect systemd hardcodes version numbers in direct calls instead of going through e.g. libdevmapper - going through a library such as libdevmapper that hanmdles the kernel versions bettrer would also take care of this issue, at least for current stretch. Thanks for your consideration. -- Package-specific info: -- System Information: Debian Release: 9.0 APT prefers testing APT policy: (990, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.4.47-040447-generic (SMP w/8 CPU cores) Locale: LANG=C, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages systemd depends on: ii adduser 3.115 ii libacl1 2.2.52-3+b1 ii libapparmor1 2.11.0-2 ii libaudit1 1:2.6.7-1 ii libblkid1 2.29.1-1 ii libc6 2.24-9 ii libcap2 1:2.25-1 ii libcryptsetup4 2:1.7.3-3 ii libgcrypt20 1.7.6-1 ii libgpg-error0 1.26-2 ii libidn11 1.33-1 ii libip4tc0 1.6.0+snapshot20161117-5 ii libkmod2 23-2 ii liblz4-1 0.0~r131-2+b1 ii liblzma5 5.2.2-1.2+b1 ii libmount1 2.29.1-1 ii libpam0g 1.1.8-3.5 ii libseccomp2 2.3.1-2.1 ii libselinux1 2.6-3 ii libsystemd0 232-18 ii mount 2.29.1-1 ii util-linux 2.29.1-1 Versions of packages systemd recommends: ii dbus 1.10.16-1 ii libpam-systemd 232-18 Versions of packages systemd suggests: ii policykit-1 0.105-17 pn systemd-container <none> ii systemd-ui 3-4 Versions of packages systemd is related to: pn dracut <none> ii initramfs-tools 0.127 ii udev 232-18 -- Configuration Files: /etc/systemd/logind.conf changed [not included] -- no debconf information
