Hi,

I'm successfully up to 5.3-STABLE / RELENG_5 as of today :)

In order to build my kernel I had to leave out apic, even though I had
options SMP...has something changed?

# make buildkernel KERNCONF=mybox

config: Error: device "apic" is unknown
config: 1 errors
*** Error code 1

Stop in /usr/src.
*** Error code 1

Stop in /usr/src.
mybox# grep apic sys/amd64/conf/NOTES 
# The apic device enables the use of the I/O APIC for interrupt delivery.
# The apic device can be used in both UP and SMP kernels, but is required
# for SMP kernels.  Thus, the apic device is not strictly an SMP option,

Did smp successfully make it into my kernel?

mybox# uname -a
FreeBSD mybox 5.3-STABLE FreeBSD 5.3-STABLE #0: Tue Dec  7 15:35:28

mybox# sysctl -a | grep -i smp

Thanks for any help,
