crash ardour 5.4.

dear friends,
i am using ubunutu studio and before KX Studio, and i have a lot of problems with ardour 5.4.; it crashes a lot, the most after importing various wavs, though i have four 3,4 GHz CPU (i put them all to PERFORMANCE, switched off ONDEMAND); ardour 4 worked pretty well for me, but this is really a continuing crash, i tried various linux distros, and problem stays the same;
thanks for help,

thanks, bro!

anyhow, with ardour 4 i didnt have this problems …
