[10:56] <genkgo> infinity: Yesterday you helped me upgrading to 3.19 kernel. This solves the problem that my VPS does not switch to read-only while running VSS snapshots. However, yesterday suddenly there are no more VSS freeze and thaw logs. There is no reason why I do not see them anymore. The VSS daemon appears to running (ps -aux |grep vss). The only additional log I have is "Clocksource tsc unstable (delta = -75591956 ns)".
[10:58] <genkgo> Fortunately, my vps is doing well. At least there are no read-only troubles and I believe other processes are running fine.
[16:26] <kenjo> So is the removal of /dev/mem in 4.x intentional ??  demidecode needs this to work.
