Public bug reported:
With kernel 4.15.0-151 the system very often (up to several times an
hour) hangs up completely and doesn't react to input of any kind. It
then has to be restarted the hard way (i.e. by prssing the power button
for several seconds).
At other times a message is displayed, saying that the file system is
read-only, nothing can be saved to the hard disk anymore (i.e. no files
written by applications like QtCreator).
These problems haven't been observed after booting kernel 4.15.0-147.
