--- Begin Message ---Package: zfs-dkms Version: 0.8.1-4~bpo10+1 Severity: critical Tags: upstream Justification: causes serious data loss Dear Maintainer, recently I have noticed some instability on one of my machines. The mprime (https://www.mersenne.org/download/) Torture Tests would occasionaly show errors like "FATAL ERROR: Rounding was 0.5, expected less than 0.4 Hardware failure detected, consult stress.txt file." random commands would occasionaly segfault. While trying to narrow down the problem I have replaced the PSU, RAM and the CPU. Multiple hour long runs of memtest86 did not show any problem. Finally I was able to narrow down the reads from ZFS volumes as the trigger for the instability. Scrubbing the volume would cause mprime to error out especially quickly. As a workaround I switched the SIMD acceleration off by piping "scalar" to /sys/module/zfs/parameters/zfs_vdev_raidz_impl and /sys/module/zcommon/parameters/zfs_fletcher_4_impl and that made the system stable again.
