Comment # 37 on bug 931964 from Roland Bernet

It seems not hardware related. It happened mostly on three machines and for
some others very sporadically. It seems more related to I/O (mainly NFS) or
frequent remote logins (main differences to other servers/machines). This was
all with systemd-208.

Here the info for the three machines:

Hardware name: ASUSTek Computer INC. RS300-E7-PS4/P8B-E Series, BIOS 5008

With systemd-210 I have seen it only once until now.
