 Hello!
 
 I think I've the malefactor.
 I've compiled a new kernel without additional optimizations which I had 
 before:
 makeoptions    COPTFLAGS="-O2 -pipe -funroll-loops -ffast-math"
 
 I've restarted the system more times and generated high IO over more 
 hours and I hadn't any warnings...
 
 Now I'll try to figure out which of these options causes the "bug" and 
 if it also works with SCHED_ULE. Because with SCHED_ULE and all 
 above-mentioned optimizations I had more warnings than with SCHED_4BSD 
 and the same optimizations.
 
 Regards,
 Lukas
