This sounds like a kernel bug rather than anything that Rosegarden can influence. Changing the timer setting in Rosegarden just makes Rosegarden tell the ALSA kernel layer to use a different timer, it makes no other difference to Rosegarden's own behaviour. There is a long history of unstable interactions between RT kernel patches and the different ALSA sequencer timers.
