I believe that I answered that question in an earlier post, but for what it's worth, the answer is an emphatic "yes": PREEMPTION is turned on in GENERIC (along with _KPOSIX_PRIORITY_SCHEDULING and SMB), and my (posted) kernel config is essentially include GENERIC, turn off I486_CPU and I586_CPU, and override SCHED_ULE (or not). So unless the config include mechanism is broken, I've got PREEMPTION, (and so has nearly everyone else). Cheers, Andrew
