Bug#949256: linux-image-5.4.0-2-amd64: zram-tools blocks shutdown (regression since 5.2)
Package: src:linux Version: 5.4.8-1 Severity: normal Dear Maintainer, After I did apt-get dist-upgrade which led to installing kernel 5.4, i noticed that shutdown of my laptop started to take forever, with the messages you can see on the following photos https://drive.google.com/drive/folders/18CTuZTs49j2X2vMGMqA-P9czLjMKDNHX?usp=sharing either removing zram-tools package or using linux-image-5.2.0-3-amd64 @ 5.2.17-1 which I had before the dist-upgrade makes the problem go away. Since 5.4 changelog mentions zram, I suspect that it was the kernel that introduced this regression. -- Package-specific info: ** Version: Linux version 5.4.0-2-amd64 (debian-ker...@lists.debian.org) (gcc version 9.2.1 20200104 (Debian 9.2.1-22)) #1 SMP Debian 5.4.8-1 (2020-01-05) ** Command line: BOOT_IMAGE=/boot/vmlinuz-5.4.0-2-amd64 root=UUID=d814e87a-f8b6-4af0-82af-f910803c8ae7 ro quiet elevator=noop ** Not tainted ** Kernel log: [4.920496] systemd[1]: Mounted FUSE Control File System.
