Compilation went fine. I found the usual warning in /usr/src/sys/kern/kern_poll.c concerning device polling in SMP kernels and removed it. To finally enable the feature one have to set the sysctl kern.polling.enable to value '1'. The only problem is that 5.3-BETA5 doesn't know about it: sysctl: unknown oid 'kern.polling.enable' Any advice is highly appreciated. Regards, Stephan.
