I have uploaded full netconsole logs with the options you suggested: http://onelanftp.co.uk/bscott/netconsole.noreboot.txt http://onelanftp.co.uk/bscott/netconsole.reboot.txt Here is the output of mount from the same system after power-fail reboot: # mount /proc on /proc type proc (rw,relatime) /sys on /sys type sysfs (rw,relatime) udev on /dev type devtmpfs (rw,nosuid,relatime,size=509736k,nr_inodes=127434,mode=755) devpts on /dev/pts type devpts (rw,relatime,gid=5,mode=620,ptmxmode=000) tmpfs on /dev/shm type tmpfs (rw,relatime) tmpfs on /run type tmpfs (rw,nosuid,nodev,noexec,relatime,mode=755) /dev/mapper/NTBgroup-System4 on / type ext4 (rw,noatime,user_xattr,barrier=1,data=ordered) tmpfs on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,relatime,mode=755) cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,release_agent=/lib/systemd/systemd-cgroups-agent,name=systemd) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/cpu type cgroup (rw,nosuid,nodev,noexec,relatime,cpu) cgroup on /sys/fs/cgroup/cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event) systemd-1 on /dev/mqueue type autofs (rw,relatime,fd=23,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /dev/hugepages type autofs (rw,relatime,fd=24,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=25,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /sys/kernel/debug type autofs (rw,relatime,fd=26,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) systemd-1 on /sys/kernel/security type autofs (rw,relatime,fd=28,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) tmpfs on /media type tmpfs (rw,nosuid,nodev,noexec,relatime,mode=755) /dev/mapper/NTBgroup-Data on /data type ext4 (rw,noatime,user_xattr,barrier=1,data=ordered) /dev/sda1 on /boot type ext3 (rw,noatime,errors=continue,user_xattr,acl,barrier=0,data=ordered) Barry
