Sorry, the question on the end slipped out of my screen and my attention... It is CONFIG_PREEMPT_RTB=y as you already figured out. > Ah, ok so clue came late and PREEMPT_RTB is basically a half-way house > between PREEMPT and PREEMPT_RT (_FULL).

I am currently testing this stuff on an arm1136jfs with 533Mhz. The CONFIG_PREEMPT_RT _FULL with the softirqs is to slow on this machine to handle a 9.6khz interrupts. I think mainly because of the additional context switch caused by the softirqs. But going to CONFIG_PREEMPT_RTB we are right on the sweet spot for this machine. We observed worst case usermode latencies for 1.2khz and are able to handle 9.6khz hardirq with reasonable cpu load. So the CONFIG_PREEMPT_RTB is the right option for puny systems like arm1136. Annotation: i was interrupted while writing this mail, so the below part is outdated by other mails from you.

I just thought that that it might be some changes in 3.0.1 compared to 3.0 but i noticed that the rt8 patch also cleanly applys against 3.0 and i tested this The butsplat looks very similar to my other bugreports sent today.
