That is not the case:
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 950M 350M 551M 39% /
/dev/sda1 99M 38M 57M 40% /boot
tmpfs 475M 0 475M 0% /dev/shm
/dev/sda6 487M 44M 428M 10% /home
/dev/sda8 4.3G 3.8G 386M 91% /usr
/dev/sda7 872M 452M 385M 55% /var
/dev/sda10 459G 455G 3.7G 100% /Myth
Restarting mythbackend helped and could also explain the memory leak
hint that was posted.

powertop says mythbackend causes the majority of interrupts from C2
state. (about 55% for do_nanosleep (hrtimer_wakeup) )
Wakeups-from-idle per second : 527.3
Is that normal?

Don't use scaling as I only have 1.2 Ghz in that tiny system. Also in
the past the scaling wasn't too stable as it is in my other systems.

Thanks for posting your suggestions/ideas.
Kind regards,
