Up-to-date Debian 7.6 here,
I've noticed that after coming back to work after lunch break hour (no
suspend, just screen lock), Dolphin freezes. Even new Dolphin instances
locks up.
I am not sure how it fixes up, some times I just restart system.
I've tried to run:
$stat /media/public
And kernel.log printed this (after some time):
Sep 4 13:31:50 acer kernel: [78120.680627] INFO: task stat:26929 blocked
