is it using a backported KPTI patch set, respl. is it possible to
disable it by booting with nopti [1]? I don't have the time to read
changelogs at the moment.

Since a DAW not necessarily is connected to the Internet at all, but
requires best performance, disabling might be better, than using the
KPTI patch set and suffering from loss of performance. I read a German
article about extreme performance loss for SSD usage, but the article
doesn't mention Linux.

However, I didn't make tests, just installed a few
minutes ago.
