I cannot find anything relevant open in / for write while this is going
on (/ is the SSD on this system). The filesystem is mounted noatime,
nodevmtime, but I suspect it's having metadata written out when it shouldn't
anyway. I note that others have reported laptop disks spinning up recently
for no obvious reason...
