Otherwise we risk that the 2nd part of the line ends up on a line of
it's own, which means a kernel dmesg line without a log level. This
then upsets the dmesg checker in piglit.
Only really happens in some of the truly nasty igt testcases which
race cache dropping (through debugfs) with other gem operations.
