Hi,

suspecting systemd, as it worked before installing systemd, and that sounds
like a typical power management thing:

After installing systemd, often dirty pages stop being flushed out and
remain dirty for minutes, then the first read access to a sector that is
not cached then writes out all buffers synchronously.

While that is somewhat sensible for a laptop with a harddisk on battery
power, I find it quite annoying as I have an SSD and enough memory for it
to collect a few hundred MB of unwritten data.

File system is ext4 with trim option set.

Systemd does not fiddle with those settings. It's more likely a tool like laptop-mode-tools or pm-utils. I suggest looking in that direction.

reassign 781287 pm-utils
thanks

Hi,

indeed pm-utils is the culprit here.

There is no obvious way to turn this feature off and have it remain
off through upgrades.
