There seems to be something odd with Linux image 6.1 preempt
On a Ryzen 5, Rosegarden keeps randomly losing the transport timer
sometimes freezing for nearly a second (then blasts poor yoshimi with bunches
of notes on all 16 channels). This doesn't happen with the 'normal' 6.1
kernel,
nor does it happen with 5.10 preempt.
However the exact same setup on an older Intel Pentium has no problems at all.
Have you turned off hyperthreading on the Ryzen system (usually called SMT in
BIOS settings on AMD)? I keep SMT turned off on my Ryzen systems to avoid
possible scheduling problems. So far no problems with 6.x kernels with dynamic
preempt enabled.
