I'm seeing - User Interface corruption under X. That shows as random processes crashing with SIGFPE (interestingly, often two unrelated X processes crash at the same time -- sometimes one of them is the server) or SEGV,
I just switched to -test11 and turned off preemption. I don't see any more crashes or weird behavior, but now performance sucks -- console scrolling (frame buffer) stalls for seconds, keyboard repeat likewise, and the X server suddenly decides it wants twice the CPU (60% instead of 30%).
I'll rebuild test11 with preempt and check whether there are any changes. (Yes I know, changing two variables at the same time was somewhat stupid.)
