Bug#900821: linux-image-4.9.0-6-amd64: apache reads wrong data over cifs filesystems served by samba
Hi,
I am facing this problem with debian stable, but kernel from backports:
ii linux-image-4.19.0-0.bpo.1-amd64-unsigned 4.19.12-1~bpo9+1
amd64 Linux 4.19 for 64-bit PCs
Linux version 4.19.0-0.bpo.1-amd64 (debian-kernel@lists.debian.org) (gcc
version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1)) #1 SMP Debian
4.19.12-1~bpo9+1 (2018-12-30)
The problem appear around twice a day while copying data via rsync to
software raid disk array.
